I've read a copy of Mendeleyev's paper for Russian Chemistry Society meeting of 15 October 1876. This translation is very close to Mendeleyev's words.
And there is another well-known Mendeleyev's quote about petroleum: "Нефть - не топливо, топить можно и ассигнациями" ("To burn oil means to stoke a stove with banknotes" - translation taken from http://www.opec.ru/library/article.asp?tmpl=def_article_print&d_no=2021&c_no=66&c1_no=).
Nature says 14 is an error, but what is the source for the supposedly correct 13? What are the names of the previous 12? Also were there any still-births in the family and do they get counted? My grandmother had a still-born girl and she was given a name, Anna, I believe, before she was buried. Hackwrench 01:50, 16 December 2005 (UTC)

It seems likely that many of the 'mistakes' found in both EB and WP are significant omissions [both in this and in other biographies]. We should be able to get closer to 19 than the above list, however. +sj + 04:47, 16 December 2005 (UTC)

"... he married Feozva Nikitichna Leshcheva; the marriage ended in divorce, though not before he had married Anna Ivanovna Popova." If this is true, I think we need to state explicitly that he was a bigamist. Bigamy is hardly an insignificant or trivial matter in Russian society. JackofOz 21:46, 19 January 2006 (UTC)

The number of Mendeleev's siblings is a matter of some historical dispute. When the Princeton historian of science Michael Gordin reviewed this article as part of an analysis of the accuracy of Wikipedia for the December 14, 2005 issue of Nature, he cited as one of Wikipedia's errors that "They say Mendeleev is the 14th child. He is the 13th surviving child of 17 total. 14 is right out." However in a New York Times article from January 2006, it was noted that in Gordin's own 2004 biography of Mendeleev, he also had the Russian chemist listed as the 17th child, and quoted Gordin's response to this as being: "That's curious. I believe that is a typographical error in my book. Mendeleyev was the final child, that is certain, and the number the reliable sources have is 13." Gordin's book specifically says that Mendeleev's mother bore her husband "seventeen children, of whom eight survived to young adulthood," with Mendeleev being the youngest. See: George Johnson, "The Nitpicking of the Masses vs. the Authority of the Experts" New York Times (January 3, 2006) ( online); "Supplementary information to accompany Nature news article 'Internet encyclopaedias go head to head' (Nature 438, 900-901; 2005)", posted on the Nature website December 22, 2005 ( PDF); Gordin 2004, p. 178.
This was one of the 42 articles that Nature (journal) compared with the Brittanica version. ( Link here) Somebody has already corrected the 13th child bit, but it also states that this article "incorrectly describes how Mendeleev's work relates to that of British chemist John Dalton." I don't know enough on the subject to figure out what they are talking about, but I would guess somebody here does. Cheers, Banyan Tree 20:02, 14 December 2005 (UTC)
The paragraph about this article says "The most error-strewn article, that on Dmitry Mendeleev, co-creator of the periodic table, illustrates this. Michael Gordin, a science historian at Princeton University who wrote a 2004 book on Mendeleev, identified 19 errors in Wikipedia and 8 in Britannica. These range from minor mistakes, such as describing Mendeleev as the 14th child in his family when he was the 13th, to more significant inaccuracies. Wikipedia, for example, incorrectly describes how Mendeleev's work relates to that of British chemist John Dalton. "Who wrote this stuff?" asked another reviewer. "Do they bother to check with experts?"" [1] WAS 4.250 05:40, 15 December 2005 (UTC)
As best that I can make out about the Dalton comment: Dalton pointed out that compounds (two or more elements) arose from fixed ratios. For example, water was some fixed ratio of hydrogen to oxygen. In contrast, a single-phase solution can cover a wide, continuous range of concentrations, from zero to saturation, thus no fixed ratio of solute to solvent applies. In metalurgy, you can make "solid solutions" or alloys where you can go between all of one metal and all of some other metal. One example: brass, which is copper and zinc. There is no brass "molecule", thus no fixed ratio. -- Pinktulip 02:32, 29 January 2006 (UTC)
It is not perfectly obvious from the text that good 'old Dmitri committed adultery. It is a service to the reader to make this clear. -- Pinktulip 23:10, 6 February 2006 (UTC)
(note that all dates are in the old Russian style, using the Julian calendar) Because his first marriage had "started to sour", when he moved Petersburg to be at the center of the Russian scientific world at St. Petersburg University, he left his family at their estate near Moscow. He began courting Popova in August of 1876, becaming despondent and even contemplating suicide when she left for Italy in December of 1880. He followed her to Rome in 1881 and threatened to commit suicide if she didn't agree to marry him. His wife then sued for divorce on the grounds of adultery; their marriage ended officially on February 23, 1882. (His first child with Popova was born December 1881, but "postdated to the spring of 1882). However, his second marriage was technically illegal because the Russian Orthodox Church required a period of seven years before remarriage after divorce, making him "a publicly acknowledged bigamist". His failure to be elected to the Russian Academy of Sciences (he was being considered in the late 1870's into the early 1880s) was partly (among many other reasons) a result of his divorce and the surrounding controversy.
As Gordin describes it, it was more an issue of religion and public morality than law, per se.
I hope that helps.-- ragesoss 23:59, 6 February 2006 (UTC)
The results of what exactly Nature suggested should be corrected is out... italicize each bullet point once you make the correction. -- user:zanimum
Reviewer: Michael Gordin, Assistant Professor of History of Science, Princeton University, New Jersey, USA.
In general, please don't simply blindly make the correction. For one thing, reviewers can sometimes make mistakes. For another thing, you could end up correcting the symptom but not the disease—if a particular statement was added without checking, then it could be that the problems in the surrounding text go deeper than what the reviewer pointed out. —Steven G.

His last name is Mendeleev.
As Mendeleev published his ОПЫТЪ СИСТЕМЫ ЭЛЕМЕНТОВЪ. осңованной на ихъ атомкомъ вѣсѣ и химическомъ ходствѣ, the Speculative System of Elements, based on their atomic weights and chemical similarities, in 1869, the spelling reform of 1918 doesn't influence him. The publication is signed with Д. Менделѣевъ. Therefore, it would be IMHO appropriate to write the surname in the original spelling. 80.146.109.154 15:34, 22 July 2007 (UTC)
I tried to correct this but the faithful wikipedia folk decided to put it back to the incorrect form... To wit: I said 40% ethanol is 1 part ethanol and 4 parts water (turns out it is 1 part ethanol, 5 parts water) -- not 2 like the page wants to extol....
Consider: 100mL of vodka. If 60% (60mL) is water, water density is 1g per mL, so it is 60g of water. H2O = 1+1+16 = 18g/mole so we have 3.33 moles of water. 40% ethanol is 40 mL of ethanol. At a density of 0.77g/mL we have 30.8g of ethanol. Ethanol is CH3-CH2-OH or 12+3 + 12+2 + 16+1 or 46g/mole -- so we have ~.67 moles of ethanol. Total moles = 4. 0.67 is 1 part of 6, or, 1 part ethanol 5 parts water -- I will change it again now. —Preceding unsigned comment added by 76.172.56.48 ( talk) 07:18, 19 December 2007 (UTC)

Mendeleev has NOT invented vodka. Please remove this bullshit! —Preceding unsigned comment added by Pavelgubarev ( talk • contribs) 10:28, 3 September 2008 (UTC)
Anyway, the statement "vodka should be produced in the ratio of one molecule of ethyl alcohol diluted with two molecules of water, giving a dilution by volume of approximately 38% alcohol to 62% water" is wrong. If you (that's a "generic you") do the calculations, you'll see that to have two molecules of water per molecule of ethanol you need to have 62% ethanol and 38% water--exactly the opposite of what the article says. And this is pretty far from the composition of most current vodkas, so there's something fishy about the story. -- Itub ( talk) 16:53, 29 September 2008 (UTC)
I removed this paragraph:
The classic Russian and Polish vodka is 40% ABV (USA 80 proof). This can be attributed to the Russian standards for vodka production introduced in 1894 by Alexander III from research undertaken by the Russian chemist Dmitri Mendeleev. According to the Vodka Museum in Moscow, Mendeleev found the perfect percentage to be 38. However, since spirits in his time were taxed on their strength, the percentage was rounded up to 40 to simplify the tax computation.
Because it looks like it was plagiarized. If a real source can be found, and the language cleaned up, it would be useful to include. John Duncan ( talk) 00:53, 25 March 2009 (UTC)
What is the source of this information?
I have noted this quote on a couple of unofficial sites on the Internet, which could account for both Mendel and Sokolov being Jewish names in general, the latter often associated with this area. Can anyone verify this from an authoritative biographical source?
Mendeleev had no Jewish ancestors. His grandfather was a Russian priest Pavel Sokolov - this is one of the most common Russian surnames. While studying at the seminary, his sons have received different names - this is an old tradition of the clergy. Dmitri's father - Ivan received a sobriquet Mendeleev (on behalf of landowner Mendeleev, next to the possession of which they lived), about his brothers - see in the RU-wiki (where indicated authoritative sources). I am archivist, and I researched the life of Mendeleev 38 years. Merchants and industrialists Kornilevy - the ancestors of the mother a scientist. On this line there is a hypothesis of Kyrgyz origin.
Error reason: Origin name of landlord also has the interpretation of Mendeleev as homonym surname Mendel: in Russian surname first part - word "men" "obmen" "menjat(ь)" - exchange (in en.), and second part - word "dele" - suffix form of word - "delo" - do (in en.). (presumably: the ancestors of Mendeleev landowner involved the replacement of horses on the long period road).
It is Mendeleev's arms - not chemist D. Mendeleev.
Best regards Serge Lachinov ( talk) 19:01, 31 July 2009 (UTC)
Mendeleev's grandfather Pavel Maximovich Sokolov was the priest of the Russian Orthodox Church in a small village of Tikhomandritcy (2 km away from the Udomlya lake, Tver' region, Russia). According to the church books, four of his children, Timofey, Natalya, Tatyana and Praskovya, were given the family name 'Sokolov,' whereas Alexander was recorded as Tikhomandritckii, Vasiliy - as Pokrovskiy, and Ivan - as Mendeleev.

Name Mendel-eev sounds very jewish. Like Felix Mendelson or Menachem Mendel Schneerson. Does Mendeleev has jewish roots?
Allegations of racism and "antisemitism" are unfounded, and quite unhelpful. The Cryptojew is a well-established part of Jewish history, ie) Murano Jews in Spain & the Dönmeh in Turkey. This phenomenon also occurred in Russia. What's important for this article is whether Mendeleev's father was, in fact, an ethnic Jew. Pashute pointed out that, according to the first citation, Mendeleev's father's ethnicity is not 100% known, it may be in doubt. Thus, the sentence describing Mendeleev's father's ethnicity ought to be removed or, at least, modified to express uncertainty.-- Bureaucracy ( talk) 01:11, 10 August 2009 (UTC)

The following sentence needs to be corrected: "Mendeleev became Professor of Chemistry at the Saint Petersburg Technological Institute and Saint Petersburg State University in 1863" According to on-line versions of "Great Soviet Encyclopedia", and "Encyclopedia Britannica", Mendeleev did not become a Professor at either of these institutions at 1863. Moreover, at Saint Petersburg State University, he was at first a professor of chemical technology. Only later, in 1867, he became the professor of General Chemistry. I would rewrite that as: "In 1864, Mendeleev became a professor at the Saint Petersburg Technological Institute. In 1865, he was also appointed as a professor at the University of Saint Petersburg (now Saint Petersburg State University)." In addition to the two encyclopedias, I also checked that information in: 1. the on-line supplementary material to the article in "Nature" (Nature 438, 900-901; 2005). 2. the biography of Mendeleev by L. A. Chugaev, available in parts on-line at:

As a user already pointed out (see below) the russian wikipedia site holds more information. Among others it claims, that all of the "myths" (Mendeleevs definition of "the" formula, his "law" of setting 38% and/or 40% as ideal ratio) are wrong. Nevertheless his dissertation (doctoral thesis) did cover the topic of mixing spirits (in general, not explicitly vodka!) with water though at HIGH degrees -around 70%!!
Again - it's just what i read on the russian site. But the "reference" (russianfood.com) on this site does NOT seem reliable to me. Hence I suggest to just write that Mendeleev's dissertation covered the mixture of water and spirits which apparently got mixed with/expandend by urban legends.

Many Russians I have talked to have said that the Russian vodka "Russian Standard" is actually the formula for 'the best' vodka, as developed by Mendeleev.
Has anyone else heard this claim? And how likely is it to just be the company’s propaganda and/or simply obliquely related to his work? -- Jowe 01:11, 6 March 2006 (UTC)
Reply on Vodka -- if someone can make this more suitable for the article (minus the sarcasm), please go ahead. It is all true: -- We all know that he discovered the periodic table of elements, on which all modern science is based. But few people know how his scientific career began and the "inspiration" (as in "spirit") that preceded the invention of the periodic table. He single-handedly invented...vodka! For his doctoral dissertation in 1865, young Mendeleev decided to study in detail the process of mixing water and alcohol. (Hmmm?!) I guess he spent a great deal in "research" and found out that there was a "compression of mixture", i.e. that the volume of the solution was smaller than the sum of two original volumes (Ha!) I guess the combined volume was smaller, even before all the tasting and sipping :-) The largest compression of the mixture was reached when 45.88% (mass units) of anhydrous alcohol and 54.12% of water were mixed. This is what is now called 40° vodka (80 proof). As a result, 1 liter of 40% vodka weighs 951 grams and vodka in Russia is often measured and sold not by volume (ml), but by weight (grams). To be precise, Mendeleev thought the perfect percentage to be 38%, but since spirits were taxed on their strength, the percentage was rounded up to 40% to simplify computations. As 40% vodka was considered optimal by the professor, the emperor of Russia made him a head of a special commission, a patent was filed and this was introduced as the national standard for vodka which was put in place around 1894-1896. Look it up, if you don't believe me! Bibliographical reference: О соединении спирта с водою "O soedinenii spirta s vodoi" ["On Mixtures of Alcohol with Water"], St. Petersburg, 1865, reprinted in D. Mendeleev, Sochineniia [Collected Works], Izd. Akademii Nauk SSSR, Leningrad, 1949, Vol. 4, 1-52.
The above contradicts the article on russian wikipedia. Namely, Mendeleev studied the alcohol-water solutions irrespective to their use as drinks. By the way, the accurate physical description of such processes remain to be very problematic till now. The proportion 40% was chosen from the point of view of convenience: it is close to 2:3 ratio (probably, by volume - which is simpler to prepare).
The top bar says all the 19 errors have been fixed but under the "Errors ID'd by Nature, to correct" only the first error is Italized. So are they really fixed or did they just forget to Italize the list of errors in the discussion page? ..-Random viewer.
You have got to be kidding me. Everyone knows that Mendeleyev published research on vodka. However Russian Standard or Russkiy Standard in Russian is just one of the hundreds of post-1991 vodkas produced in post-USSR countries, with multicoloured labels and stupid names like "Vodka Putin" or "Prince Igor" etc which have nothing to do with original pre-1917 Russian vodkas. Believe me, since I have tasted Soviet and Russian vodkas since 1986. The most memorable was called Vodka Black Death (Chernaya smert) and was sold in 1993-1995 in metal cans (like beer) in Moscow in every corner's kiosk and tasted very close to acetone. The good part I did not turn blind after drinking such stuff. Rozmysl ( talk) 06:32, 14 May 2012 (UTC)
As for selling vodka in grams in Russia, this is not true. In Russia vodka is sold in milliliters. On the bottle labels you can find either eg. 500 mL or 0,5 L but never grams. Selling liquids in grams is very problematic anyways, how do you imagine it? Using scales in bars? Russia and former USSR is very thorougly standardized country, and all units, sizes, weights etc. are very strictly standardized, so in Russia nothing can be sold "sometimes in grams, sometimes in ml", it is either ml or grams. The truth is, in conversational language people rather say "100 grams of vodka" but not "100 milliliters of vodka", however it still measured in ml. This may be the origin of this misunderstanding.

'Mendeleev' is a direct transliteration of a Russian name 'Менделеев' (you can install Russian fonts and check their similarity), but the correct transcription is 'Mendeleyev'. I'm a native Russian speaker, BTW.
"Mendeleyev" produces 326,000 ghits, "Mendeleev" 354,000. So it's far from clear cut. WP:RUS advises us to render Russian e as e, except "after vowels", where it becomes ye. That's why, for example, nobody's ever heard of Rudolf Nureev, but everybody knows about Rudolf Nureyev. Same for Sergei Taneyev, Fadeyev, and so on. May we please have Dmitri Mendeleyev as the primary title, with Dmitri Mendeleev as the redirect, rather than the other way around? -- Jack of Oz ... speak! ... 09:08, 22 May 2010 (UTC)
Correct would be Mendeleyev since it corresponds to Cyrillic Менделеев. Mendeleev would correspond to Cyrillic Менделеэв. Cyrillic has two letters E: one is E, same as Latin E, the other is Э. In the beginning of the word or after a vowel E is pronounced like "YEH" and Э is pronounced like "EH". Spelling Mendeleev would mean pronouncing it "Men-deh-leh-ehv" however the true pronounciation is Men-deh-leh-yev. Geographs are very good at this, if you want to understand rules for converting Cyrillic names to Latin, look at a map of Russia. However I do not expect anybody to agree with me, since even most Russians will have no clue how to transliterate their names to Latin properly. Take for example name of the country on Russian postal stamps: they spelled it Rossija (in Latin) for more than 10 years until recently, as apposed to proper Rossiya, since most Russians know Latin (not English) names for Latin letters like "a, be, tse, de, ye, ef, zhe, ash, i, yot" etc, this pronunciation is used in Russian schools to teach kids math. So J for Russians traditionally is "yot" and represents sound "Y" similar to C representing sound TS (same sound as in German word Zeit etc). Rozmysl ( talk) 06:44, 14 May 2012 (UTC)
In Russia there is city Mendeleyevsk, you can find it via Google maps, this is the correct spelling. Using Google hits to justify spelling is ridiculous. Rozmysl ( talk) 06:50, 14 May 2012 (UTC)

The Periodic Table is actually laid out by an element's Atomic Number. Previous attempts had always laid it out by atomic weight- Did Mendeleev ever realise this?

Hello. Mendeleev was not "the co-creator" of the periodic table. The Royal Society gives him the credit that is his due. I plan to remove the co-creation sentence in about a month after leaving time for objections here.

The article references indicate not only was he a Christian but remained in the Orthodox Church until he died. Some may say he was or was not very devout. That doesn't make him a "former Christian", so the tag is inappropriate. — Preceding unsigned comment added by 73.38.0.54 ( talk) 04:04, 10 April 2020 (UTC)
The intro says that "He used the Periodic Law ... to predict the properties of eight elements that were yet to be discovered", but the article does not specify which eight. The Periodic Table section does specify three as ekasilicon (now Ge), ekaaluminium (now Ga) and ekaboron (now Sc). The See also section leads to the article Mendeleev's predicted elements, which adds ekamanganese (now Tc) clearly to the list and mentions a few others in passing but it is not clear which are included in the eight. The infobox has a figure of Mendeleev's 1871 table with about 20 blank lines for extra elements, but which did Mendeleev actually mention?
Could someone add an explicit list of the eight elements which Mendeleev actually predicted? Dirac66 ( talk) 18:38, 17 April 2021 (UTC)

In popular culture: Dmitri Mendeleev is portrayed in the Russian 2021 Netflix movie [ Skates] as an independent, wise and somewhat wild character. He stands in stark contrast to the restrictive Russian University establishment. It is due to his recognized brilliance and statue that he is able to lend support to the heroine in her quest to become the first female in the university.

Seems like it might not be so? From the abstract of two articles from Springer in 2001 --
From [1] - "Mendeleev's dream of the periodic table of elements in its completed form is apparently specious, despite repeated citations. Not only is there no dream report but evidence rests on a colleague's second-hand account. Kedrov's examination of archival material indicates (1) that Mendeleev had already discovered the periodic table before the alleged dream took place; and (2) that a dream quite plausibly occurred somewhat later that depicted an improved representation of the periodic table."
From [2] "All accounts of this event agree that he'd worked for years on the Table, produced other drafts, but that he attributed the version he was most satisfied with to a dream. It is less clear whether Kedrov is correct in his reconstruction that it was the reversal of columns vs. rows which the dream provided."
Seems like they both reference a "Kedrov". According to [3] that's Bonifaty Kedrov who doesn't seem to be mentioned anywhere in the article or have any mention of his work on Mendeleev in his article. -- "B. M. Kedrov (1903–1985) was a pioneering historian on the origin of Mendeleev’s discovery. Kedrov discovered Mendeleev’s archived materials related to his first periodic table (dated February 17, 1869) at the Mendeleev Museum in the St. Petersburg State Museum at the end of the 1940s. He then began full-fledged research on Mendeleev’s discovery of the periodic law, which culminated in the publication of The Day of a Great Discovery (Kedrov 1958) and other books which are generally reliable resources (Mendeleev and Kedrov 1958, 1960). In his meticulous reconstruction of Mendeleev’s compilation of the first periodic table, Kedrov emphasized the “one-day discovery” (February 17, 1869), and paid only scant attention to both Mendeleev’s earlier works and the social context of the discovery. At about the same time, R. B. Dobrotin analyzed Mendeleev’s earliest works, especially those of the 1850s, and argued that essential elements of the future periodic system already existed (Dobrotin 1953; Shchukarev and Dobrotin 1954). However, Kedrov’s version of the discovery had a dominant influence on Soviet history of science. In the 1970s, A. A. Makarenya cautiously expressed some doubts about Kedrov’s description of Mendeleev’s scientific works (Makarenya 1972). After Kedrov’s death, D. N. Trifonov proposed in 1990 “Version-2” of the discovery and criticized Kedrov’s “one-day version” (Trifonov 1990). Starting from a critical reevaluation of Kedrov’s research, very different reconstructions have recently been proposed."
I don't feel like I'm in a good position to judge what's true here / don't have much experience editing wikipedia, so I thought I'd put this information in the talk page and maybe things will sort themselves out as time goes on.

I've read a copy of Mendeleyev's paper for Russian Chemistry Society meeting of 15 October 1876. This translation is very close to Mendeleyev's words.
And there is another well-known Mendeleyev's quote about petroleum: "Нефть - не топливо, топить можно и ассигнациями" ("To burn oil means to stoke a stove with banknotes" - translation taken from http://www.opec.ru/library/article.asp?tmpl=def_article_print&d_no=2021&c_no=66&c1_no=).

"... he married Feozva Nikitichna Leshcheva; the marriage ended in divorce, though not before he had married Anna Ivanovna Popova."

The number of Mendeleev's siblings is a matter of some historical dispute. When the Princeton historian of science Michael Gordin reviewed this article as part of an analysis of the accuracy of Wikipedia for the December 14, 2005 issue of Nature, he cited as one of Wikipedia's errors that "They say Mendeleev is the 14th child. He is the 13th surviving child of 17 total. 14 is right out." However in a New York Times article from January 2006, it was noted that in Gordin's own 2004 biography of Mendeleev, he also had the Russian chemist listed as the 17th child, and quoted Gordin's response to this as being: "That's curious. I believe that is a typographical error in my book. Mendeleyev was the final child, that is certain, and the number the reliable sources have is 13." Gordin's book specifically says that Mendeleev's mother bore her husband "seventeen children, of whom eight survived to young adulthood," with Mendeleev being the youngest. See: George Johnson, "The Nitpicking of the Masses vs. the Authority of the Experts" New York Times (January 3, 2006) ( online); "Supplementary information to accompany Nature news article 'Internet encyclopaedias go head to head' (Nature 438, 900-901; 2005)", posted on the Nature website December 22, 2005 ( PDF); Gordin 2004, p. 178.
This was one of the 42 articles that Nature (journal) compared with the Brittanica version. ( Link here) Somebody has already corrected the 13th child bit, but it also states that this article "incorrectly describes how Mendeleev's work relates to that of British chemist John Dalton." I don't know enough on the subject to figure out what they are talking about, but I would guess somebody here does. Cheers, Banyan Tree 20:02, 14 December 2005 (UTC)
The paragraph about this article says "The most error-strewn article, that on Dmitry Mendeleev, co-creator of the periodic table, illustrates this. Michael Gordin, a science historian at Princeton University who wrote a 2004 book on Mendeleev, identified 19 errors in Wikipedia and 8 in Britannica. These range from minor mistakes, such as describing Mendeleev as the 14th child in his family when he was the 13th, to more significant inaccuracies. Wikipedia, for example, incorrectly describes how Mendeleev's work relates to that of British chemist John Dalton. "Who wrote this stuff?" asked another reviewer. "Do they bother to check with experts?"" [1] WAS 4.250 05:40, 15 December 2005 (UTC)
As best that I can make out about the Dalton comment: Dalton pointed out that compounds (two or more elements) arose from fixed ratios. For example, water was some fixed ratio of hydrogen to oxygen. In contrast, a single-phase solution can cover a wide, continuous range of concentrations, from zero to saturation, thus no fixed ratio of solute to solvent applies. In metalurgy, you can make "solid solutions" or alloys where you can go between all of one metal and all of some other metal. One example: brass, which is copper and zinc. There is no brass "molecule", thus no fixed ratio. -- Pinktulip 02:32, 29 January 2006 (UTC)
It is not perfectly obvious from the text that good 'old Dmitri committed adultery. It is a service to the reader to make this clear. -- Pinktulip 23:10, 6 February 2006 (UTC)
(note that all dates are in the old Russian style, using the Julian calendar) Because his first marriage had "started to sour", when he moved Petersburg to be at the center of the Russian scientific world at St. Petersburg University, he left his family at their estate near Moscow. He began courting Popova in August of 1876, becaming despondent and even contemplating suicide when she left for Italy in December of 1880. He followed her to Rome in 1881 and threatened to commit suicide if she didn't agree to marry him. His wife then sued for divorce on the grounds of adultery; their marriage ended officially on February 23, 1882. (His first child with Popova was born December 1881, but "postdated to the spring of 1882). However, his second marriage was technically illegal because the Russian Orthodox Church required a period of seven years before remarriage after divorce, making him "a publicly acknowledged bigamist". His failure to be elected to the Russian Academy of Sciences (he was being considered in the late 1870's into the early 1880s) was partly (among many other reasons) a result of his divorce and the surrounding controversy.
As Gordin describes it, it was more an issue of religion and public morality than law, per se.
I hope that helps.-- ragesoss 23:59, 6 February 2006 (UTC)

Reviewer: Michael Gordin, Assistant Professor of History of Science, Princeton University, New Jersey, USA.
In general, please don't simply blindly make the correction. For one thing, reviewers can sometimes make mistakes. For another thing, you could end up correcting the symptom but not the disease—if a particular statement was added without checking, then it could be that the problems in the surrounding text go deeper than what the reviewer pointed out. —Steven G.

His last name is Mendeleev.
As Mendeleev published his ОПЫТЪ СИСТЕМЫ ЭЛЕМЕНТОВЪ. осңованной на ихъ атомкомъ вѣсѣ и химическомъ ходствѣ, the Speculative System of Elements, based on their atomic weights and chemical similarities, in 1869, the spelling reform of 1918 doesn't influence him. The publication is signed with Д. Менделѣевъ. Therefore, it would be IMHO appropriate to write the surname in the original spelling. 80.146.109.154 15:34, 22 July 2007 (UTC)
I tried to correct this but the faithful wikipedia folk decided to put it back to the incorrect form... To wit: I said 40% ethanol is 1 part ethanol and 4 parts water (turns out it is 1 part ethanol, 5 parts water) -- not 2 like the page wants to extol....
Consider: 100mL of vodka. If 60% (60mL) is water, water density is 1g per mL, so it is 60g of water. H2O = 1+1+16 = 18g/mole so we have 3.33 moles of water. 40% ethanol is 40 mL of ethanol. At a density of 0.77g/mL we have 30.8g of ethanol. Ethanol is CH3-CH2-OH or 12+3 + 12+2 + 16+1 or 46g/mole -- so we have ~.67 moles of ethanol. Total moles = 4. 0.67 is 1 part of 6, or, 1 part ethanol 5 parts water -- I will change it again now. —Preceding unsigned comment added by 76.172.56.48 ( talk) 07:18, 19 December 2007 (UTC)

Mendeleev has NOT invented vodka. Please remove this bullshit! —Preceding unsigned comment added by Pavelgubarev ( talk • contribs) 10:28, 3 September 2008 (UTC)
Anyway, the statement "vodka should be produced in the ratio of one molecule of ethyl alcohol diluted with two molecules of water, giving a dilution by volume of approximately 38% alcohol to 62% water" is wrong. If you (that's a "generic you") do the calculations, you'll see that to have two molecules of water per molecule of ethanol you need to have 62% ethanol and 38% water--exactly the opposite of what the article says. And this is pretty far from the composition of most current vodkas, so there's something fishy about the story. -- Itub ( talk) 16:53, 29 September 2008 (UTC)
I removed this paragraph:
The classic Russian and Polish vodka is 40% ABV (USA 80 proof). This can be attributed to the Russian standards for vodka production introduced in 1894 by Alexander III from research undertaken by the Russian chemist Dmitri Mendeleev. According to the Vodka Museum in Moscow, Mendeleev found the perfect percentage to be 38. However, since spirits in his time were taxed on their strength, the percentage was rounded up to 40 to simplify the tax computation.

What is the source of this information?
I have noted this quote on a couple of unofficial sites on the Internet, which could account for both Mendel and Sokolov being Jewish names in general, the latter often associated with this area. Can anyone verify this from an authoritative biographical source?
Mendeleev had no Jewish ancestors. His grandfather was a Russian priest Pavel Sokolov - this is one of the most common Russian surnames. While studying at the seminary, his sons have received different names - this is an old tradition of the clergy. Dmitri's father - Ivan received a sobriquet Mendeleev (on behalf of landowner Mendeleev, next to the possession of which they lived), about his brothers - see in the RU-wiki (where indicated authoritative sources). I am archivist, and I researched the life of Mendeleev 38 years. Merchants and industrialists Kornilevy - the ancestors of the mother a scientist. On this line there is a hypothesis of Kyrgyz origin.
Error reason: Origin name of landlord also has the interpretation of Mendeleev as homonym surname Mendel: in Russian surname first part - word "men" "obmen" "menjat(ь)" - exchange (in en.), and second part - word "dele" - suffix form of word - "delo" - do (in en.). (presumably: the ancestors of Mendeleev landowner involved the replacement of horses on the long period road).
It is Mendeleev's arms - not chemist D. Mendeleev.
Best regards Serge Lachinov ( talk) 19:01, 31 July 2009 (UTC)
Mendeleev's grandfather Pavel Maximovich Sokolov was the priest of the Russian Orthodox Church in a small village of Tikhomandritcy (2 km away from the Udomlya lake, Tver' region, Russia). According to the church books, four of his children, Timofey, Natalya, Tatyana and Praskovya, were given the family name 'Sokolov,' whereas Alexander was recorded as Tikhomandritckii, Vasiliy - as Pokrovskiy, and Ivan - as Mendeleev.

Name Mendel-eev sounds very jewish. Like Felix Mendelson or Menachem Mendel Schneerson. Does Mendeleev has jewish roots?
Allegations of racism and "antisemitism" are unfounded, and quite unhelpful. The Cryptojew is a well-established part of Jewish history, ie) Murano Jews in Spain & the Dönmeh in Turkey. This phenomenon also occurred in Russia. What's important for this article is whether Mendeleev's father was, in fact, an ethnic Jew. Pashute pointed out that, according to the first citation, Mendeleev's father's ethnicity is not 100% known, it may be in doubt. Thus, the sentence describing Mendeleev's father's ethnicity ought to be removed or, at least, modified to express uncertainty.-- Bureaucracy ( talk) 01:11, 10 August 2009 (UTC)

The following sentence needs to be corrected: "Mendeleev became Professor of Chemistry at the Saint Petersburg Technological Institute and Saint Petersburg State University in 1863" According to on-line versions of "Great Soviet Encyclopedia", and "Encyclopedia Britannica", Mendeleev did not become a Professor at either of these institutions at 1863. Moreover, at Saint Petersburg State University, he was at first a professor of chemical technology. Only later, in 1867, he became the professor of General Chemistry. I would rewrite that as: "In 1864, Mendeleev became a professor at the Saint Petersburg Technological Institute. In 1865, he was also appointed as a professor at the University of Saint Petersburg (now Saint Petersburg State University)."

As a user already pointed out (see below) the russian wikipedia site holds more information. Among others it claims, that all of the "myths" (Mendeleevs definition of "the" formula, his "law" of setting 38% and/or 40% as ideal ratio) are wrong. Nevertheless his dissertation (doctoral thesis) did cover the topic of mixing spirits (in general, not explicitly vodka!) with water though at HIGH degrees -around 70%!!
Again - it's just what i read on the russian site. But the "reference" (russianfood.com) on this site does NOT seem reliable to me. Hence I suggest to just write that Mendeleev's dissertation covered the mixture of water and spirits which apparently got mixed with/expandend by urban legends.

Many Russians I have talked to have said that the Russian vodka "Russian Standard" is actually the formula for 'the best' vodka, as developed by Mendeleev.
Has anyone else heard this claim? And how likely is it to just be the company’s propaganda and/or simply obliquely related to his work? -- Jowe 01:11, 6 March 2006 (UTC)
Reply on Vodka -- if someone can make this more suitable for the article (minus the sarcasm), please go ahead. It is all true: -- We all know that he discovered the periodic table of elements, on which all modern science is based. But few people know how his scientific career began and the "inspiration" (as in "spirit") that preceded the invention of the periodic table. He single-handedly invented...vodka! For his doctoral dissertation in 1865, young Mendeleev decided to study in detail the process of mixing water and alcohol. (Hmmm?!) I guess he spent a great deal in "research" and found out that there was a "compression of mixture", i.e. that the volume of the solution was smaller than the sum of two original volumes (Ha!) I guess the combined volume was smaller, even before all the tasting and sipping :-) The largest compression of the mixture was reached when 45.88% (mass units) of anhydrous alcohol and 54.12% of water were mixed. This is what is now called 40° vodka (80 proof). As a result, 1 liter of 40% vodka weighs 951 grams and vodka in Russia is often measured and sold not by volume (ml), but by weight (grams). To be precise, Mendeleev thought the perfect percentage to be 38%, but since spirits were taxed on their strength, the percentage was rounded up to 40% to simplify computations. As 40% vodka was considered optimal by the professor, the emperor of Russia made him a head of a special commission, a patent was filed and this was introduced as the national standard for vodka which was put in place around 1894-1896. Look it up, if you don't believe me! Bibliographical reference: О соединении спирта с водою "O soedinenii spirta s vodoi" ["On Mixtures of Alcohol with Water"], St. Petersburg, 1865, reprinted in D. Mendeleev, Sochineniia [Collected Works], Izd. Akademii Nauk SSSR, Leningrad, 1949, Vol. 4, 1-52.
The above contradicts the article on russian wikipedia. Namely, Mendeleev studied the alcohol-water solutions irrespective to their use as drinks. By the way, the accurate physical description of such processes remain to be very problematic till now. The proportion 40% was chosen from the point of view of convenience: it is close to 2:3 ratio (probably, by volume - which is simpler to prepare).

You have got to be kidding me. Everyone knows that Mendeleyev published research on vodka. However Russian Standard or Russkiy Standard in Russian is just one of the hundreds of post-1991 vodkas produced in post-USSR countries, with multicoloured labels and stupid names like "Vodka Putin" or "Prince Igor" etc which have nothing to do with original pre-1917 Russian vodkas. Believe me, since I have tasted Soviet and Russian vodkas since 1986. The most memorable was called Vodka Black Death (Chernaya smert) and was sold in 1993-1995 in metal cans (like beer) in Moscow in every corner's kiosk and tasted very close to acetone. The good part I did not turn blind after drinking such stuff. Rozmysl ( talk) 06:32, 14 May 2012 (UTC)
As for selling vodka in grams in Russia, this is not true. In Russia vodka is sold in milliliters. On the bottle labels you can find either eg. 500 mL or 0,5 L but never grams. Selling liquids in grams is very problematic anyways, how do you imagine it? Using scales in bars? Russia and former USSR is very thorougly standardized country, and all units, sizes, weights etc. are very strictly standardized, so in Russia nothing can be sold "sometimes in grams, sometimes in ml", it is either ml or grams. The truth is, in conversational language people rather say "100 grams of vodka" but not "100 milliliters of vodka", however it still measured in ml. This may be the origin of this misunderstanding.

The title and the text spell his name in two different ways. One needs to be decided on and applied consistently. — Ливай | Ⓣ 17:46, 1 October 2005 (UTC)
'Mendeleev' is a direct transliteration of a Russian name 'Менделеев' (you can install Russian fonts and check their similarity), but the correct transcription is 'Mendeleyev'. I'm a native Russian speaker, BTW.
"Mendeleyev" produces 326,000 ghits, "Mendeleev" 354,000. So it's far from clear cut. WP:RUS advises us to render Russian e as e, except "after vowels", where it becomes ye. That's why, for example, nobody's ever heard of Rudolf Nureev, but everybody knows about Rudolf Nureyev. Same for Sergei Taneyev, Fadeyev, and so on. May we please have Dmitri Mendeleyev as the primary title, with Dmitri Mendeleev as the redirect, rather than the other way around? -- Jack of Oz ... speak! ... 09:08, 22 May 2010 (UTC)
Correct would be Mendeleyev since it corresponds to Cyrillic Менделеев. Mendeleev would correspond to Cyrillic Менделеэв. Cyrillic has two letters E: one is E, same as Latin E, the other is Э. In the beginning of the word or after a vowel E is pronounced like "YEH" and Э is pronounced like "EH". Spelling Mendeleev would mean pronouncing it "Men-deh-leh-ehv" however the true pronounciation is Men-deh-leh-yev. Geographs are very good at this, if you want to understand rules for converting Cyrillic names to Latin, look at a map of Russia. However I do not expect anybody to agree with me, since even most Russians will have no clue how to transliterate their names to Latin properly. Take for example name of the country on Russian postal stamps: they spelled it Rossija (in Latin) for more than 10 years until recently, as apposed to proper Rossiya, since most Russians know Latin (not English) names for Latin letters like "a, be, tse, de, ye, ef, zhe, ash, i, yot" etc, this pronunciation is used in Russian schools to teach kids math. So J for Russians traditionally is "yot" and represents sound "Y" similar to C representing sound TS (same sound as in German word Zeit etc). Rozmysl ( talk) 06:44, 14 May 2012 (UTC)
In Russia there is city Mendeleyevsk, you can find it via Google maps, this is the correct spelling. Using Google hits to justify spelling is ridiculous. Rozmysl ( talk) 06:50, 14 May 2012 (UTC)

The Periodic Table is actually laid out by an element's Atomic Number. Previous attempts had always laid it out by atomic weight- Did Mendeleev ever realise this? Surely even if he didn't, we should explain that his way of laying it out and the spaces left corresponded to the Number ie the number of protons in the atom of an element.

Hello. Mendeleev was not "the co-creator" of the periodic table. The Royal Society gives him the credit that is his due. I plan to remove the co-creation sentence in about a month after leaving time for objections here.

The article references indicate not only was he a Christian but remained in the Orthodox Church until he died. Some may say he was or was not very devout. That doesn't make him a "former Christian", so the tag is inappropriate. — Preceding unsigned comment added by 73.38.0.54 ( talk) 04:04, 10 April 2020 (UTC)
The intro says that "He used the Periodic Law ... to predict the properties of eight elements that were yet to be discovered", but the article does not specify which eight. The Periodic Table section does specify three as ekasilicon (now Ge), ekaaluminium (now Ga) and ekaboron (now Sc). The See also section leads to the article Mendeleev's predicted elements, which adds ekamanganese (now Tc) clearly to the list and mentions a few others in passing but it is not clear which are included in the eight. The infobox has a figure of Mendeleev's 1871 table with about 20 blank lines for extra elements, but which did Mendeleev actually mention?
Could someone add an explicit list of the eight elements which Mendeleev actually predicted? Dirac66 ( talk) 18:38, 17 April 2021 (UTC)

In popular culture: Dmitri Mendeleev is portrayed in the Russian 2021 Netflix movie [ Skates] as an independent, wise and somewhat wild character. He stands in stark contrast to the restrictive Russian University establishment. It is due to his recognized brilliance and statue that he is able to lend support to the heroine in her quest to become the first female in the university.

Seems like it might not be so? From the abstract of two articles from Springer in 2001 --
From [1] - "Mendeleev's dream of the periodic table of elements in its completed form is apparently specious, despite repeated citations. Not only is there no dream report but evidence rests on a colleague's second-hand account. Kedrov's examination of archival material indicates (1) that Mendeleev had already discovered the periodic table before the alleged dream took place; and (2) that a dream quite plausibly occurred somewhat later that depicted an improved representation of the periodic table."
From [2] "All accounts of this event agree that he'd worked for years on the Table, produced other drafts, but that he attributed the version he was most satisfied with to a dream. It is less clear whether Kedrov is correct in his reconstruction that it was the reversal of columns vs. rows which the dream provided."
Seems like they both reference a "Kedrov". According to [3] that's Bonifaty Kedrov who doesn't seem to be mentioned anywhere in the article or have any mention of his work on Mendeleev in his article. -- "B. M. Kedrov (1903–1985) was a pioneering historian on the origin of Mendeleev’s discovery. Kedrov discovered Mendeleev’s archived materials related to his first periodic table (dated February 17, 1869) at the Mendeleev Museum in the St. Petersburg State Museum at the end of the 1940s. He then began full-fledged research on Mendeleev’s discovery of the periodic law, which culminated in the publication of The Day of a Great Discovery (Kedrov 1958) and other books which are generally reliable resources (Mendeleev and Kedrov 1958, 1960). In his meticulous reconstruction of Mendeleev’s compilation of the first periodic table, Kedrov emphasized the “one-day discovery” (February 17, 1869), and paid only scant attention to both Mendeleev’s earlier works and the social context of the discovery. At about the same time, R. B. Dobrotin analyzed Mendeleev’s earliest works, especially those of the 1850s, and argued that essential elements of the future periodic system already existed (Dobrotin 1953; Shchukarev and Dobrotin 1954). However, Kedrov’s version of the discovery had a dominant influence on Soviet history of science. In the 1970s, A. A. Makarenya cautiously expressed some doubts about Kedrov’s description of Mendeleev’s scientific works (Makarenya 1972). After Kedrov’s death, D. N. Trifonov proposed in 1990 “Version-2” of the discovery and criticized Kedrov’s “one-day version” (Trifonov 1990). Starting from a critical reevaluation of Kedrov’s research, very different reconstructions have recently been proposed."
I don't feel like I'm in a good position to judge what's true here / don't have much experience editing wikipedia, so I thought I'd put this information in the talk page and maybe things will sort themselves out as time goes on.
