I suggest that we try for some consensus on the structure and style of articles on functional groups. July statistics show that these articles are highly consulted (within Chemistry): ether at #23, ester at #28, amine at #39, ketone at #78, carboxylic acid at #121, amide at #141. So to get the conversation going, I (or others if they have inclination) will draft a manual of style within Wikipedia:Manual of Style (chemistry) and then invite other editors to comment. I had started to heavily edit amine and ketone articles, but I will desist until we have some sort of agreement on what these articles should look like. Apologies for not checking earlier.-- Smokefoot ( talk) 23:04, 5 August 2009 (UTC)

I recently created the article
Dihydrocortisone and when I added its other names to the chembox, I saw its really hard to see where the first name ends and the second name starts (exept for a small space between them). I couldnt use a comma because the names already have commas in them so I used a semi colon but its still confusing and hard to see the different names, any suggestions?

Hello Pikiwyn. I have observed that you have created a lot of hard-core stubs (e.g. Chlorostyrene; Chloroxuron; Chlorthiamide and so on...) Though it is nice to gain more articles here on Wiki, those stubs are impo not informative. Even the CAS is not listed, what are the substances used for, how can one make them. Many gaps are not close. Just writing e. g. "Chlorthiamide is an organic compound with the chemical formula C7H5Cl2NS." is not sufficiant. On de-Wiki, we would delete them cos they are not anything close to an "article".
First I thought you were a BOT, just pasting some ChemSpider Infos here on Wiki. This is - btw - not good, since on ChemSpider they calculate some physical data. If this is true or not, well, nobody knows. It would be very, very beneficial if you wrote something more about those "organic compounds". Thanks, -- Yikrazuul ( talk) 14:11, 9 August 2009 (UTC)

We ought to revisit the merger of sugar and sucrose. Almost all of sugar is about sucrose, as indicated by the opening paragraph and to the final bit. Parts that are not about sucrose duplicate the content in carbohydrates (saccharide redirects there). So readers are not getting the best presentation, and editors are duplicating effort. I worry also that we are confusing readers. I understand that many editors are wary of merges, but this sugar-carbohydrate-sucrose overlap appears to be a serious disservice. We'd leave carbohydrate alone. Based on the current sizes of the articles, I would propose to shift sucrose content to sugar.--Smokefoot (talk) 13:32, 3 September 2009 (UTC)

Working in the field of custody transfer supervision I need to find a means of relating observed values to standard values for industrial sized amount of chemicals (range 10 000 l up to 10 000 000 l) this is traditionlayy done using density correction coefficemts so that observed volumes may be transformed in into the equvalent mass by adjusting the standard density to the apparent density. It is often difficult to obtain an authoritive value for the density correction coefficient and various values may be in use for the same material and even for a single parcel of one shipment one material. Would it be possible to include an authoritive density correction coefficeint with the other data listed for each chemical?

Since this is one of the biggest WikiProject, and that a couple of Wikipedia-Books are chemistry related, could this project adopt the book-class? This would really help WikiProject Wikipedia-Books, as the WikiProject Chemistry people can oversee books like Chemistry much better than we could as far as merging, deletion, content, and such are concerned. Eventually there probably will be a "Books for discussion" process, so that would be incorporated in the Article Alerts. I'm placing this here rather than on the template page since several taskforces would be concerned.

I realize that great articles can spring from unpromising starts, but this one is pretty strange. "Optical spectroscopy," which should describes the "color of chemicals" redirects to Spectroscopy. Color could probably use a section that contains a section on "colored chemicals." Or the article on chemical compounds could have a section on their optical properties. My recommendation would be to convert Color of chemicals into an article on aquo complexes, which would feature a list of the colors of the common aquo ions, since that is in the current Color of chemicals. The metal aquo ions (e.g. [Ni(H2O)62+) are important, and we could explain their water exchange properties, pKa's, and possibly roles in everyday life (nutrition, corrosion, catalysis).-- Smokefoot ( talk) 17:05, 13 December 2009 (UTC)
As Smokefoot says, we don't have an article on optical spectroscopy, and UV/VIS spectroscopy describes the measurement technique more than anything else. I think the regular editors of color would have an issue if we just decided to devote a large section to why ions and chemical compounds appear colored. Would anyone like to suggest a better title where an article on this subject might reside? shoy ( reactions) 19:35, 14 December 2009 (UTC)
Perhaps someone here could help with this article on a chemist. The article creator, Hezimmerman, keeps just posing his CV. It has been explained to him repeatedly that you can't do that, and another editor and I made a two-sentence stub from some of the information in the CV. Hezimmerman seems not to be getting it though, and made a complaint today that "everytime I expand it as requested, it gets deleted".

We have just connected a demo CGI to our portable Web sketcher at http://www.xemistry.com/edit/frame.html which we hope will be helpful for collecting chemical structure identifiers for the standard chemical infobox. Draw a compound (example: pyridine) in the sketcher, then press the "Compute Wikipedia Data" button in the form below.

Many polymer articles don't have an appropriate infobox. I found one with an inappropriate one too ( sodium polystyrene sulfonate). It will be nice to aggregate information about these polymers in one place. Is it possible to extend the Chembox to have a polymerbox module? Or perhaps a new box which remains consistent with our Chembox? Not being a polymer chemist, I'm not very sure of what data is important, but at the very least, the formula and identifiers should be there. -- Rifleman 82 ( talk) 12:37, 23 December 2009 (UTC)
Could this be a module in the current chembox? The main and the identifiers and properties box seem close enough (add a Tg e.g.), and some others are also appropriate (similar compounds module is useful). -- Beetstra (public) ( Dirk Beetstra T C on public computers) 17:08, 23 December 2009 (UTC)
Yes, would be a good idea. I'm wondering about the MW/formula, though. -- Rifleman 82 ( talk) 17:32, 23 December 2009 (UTC)
Molecular is not a property of a polymer in the terms of the chembox, and the formula can go into the normal field for it. The rest generally should go into ranges, or be omitted as they are often dependent on Mw/Mn (not to speak of, e.g. for polypropyle, tacticity or similar). It needs some creativity, but it can be done. I think it would need a real polymer chemist (not one like me ..) to come up with some things that can't be done now (but if it can't be implemented in the chembox, then a polymer box will have the same problem), but I think our 'biggest' problem is going to be that isotactic polypropylene is not the same as atactic polypropylene which is not the same as syndiotactic polypropylene (e.g. I presume all three have different CASno's?), but that problem already exists for some cis/trans or stereoisomers as well (and the box also is not really capable to solve that problem). Someone up to adding Tg to the propertiesbox, I don't want to use my admin account here (but may change my mind). -- Beetstra (public) ( Dirk Beetstra T C on public computers) 22:06, 23 December 2009 (UTC)

I think that the article "Chemometrics" should start with the etymology of "chemometrics", or alternatively, it should contain a little paragraph devoted to this subject. English Chemometrics = chemo- + -metrics, from Swedish kemometri = kemo- + -metri, where the former particle may be connected to the etymology of "chemistry", and the latter to the word "metrics" or other words having -metrics.

That some elementary quantum theory is necessary to calculate specific heat capacities from first principles, is an undergraduate textbook subject. For example, my own (dated-- 1966!) copy of W. Kauzmann's Kinetic Theory of Gases, has a full chapter on it. He not only treats the easy cases where the equipartition theory asigns the full R/2 heat capacity per degree of freedom in gases (with a guess as to which degrees will be fully excited and which fully frozen out) but also treats the harder cases in which either rotational or vibrational modes are only partly participating, so that heat capacities are intermediate. Example: chlorine has a Cv heat capacity of 2.5 R if no vibrational modes are exited, and 3.5 R if they all are. The observed value for 25 oC is 3.1 R in modern sources, (2.9 R in the heat capacity article, which needs changing; but 4.1 for Cp = 3.1 Cv in the chlorine article)-- right in the middle of these two equipartitial values. The quantum theoretical value (from Kauzmann) assuming partial excited vibration is 3.1 R, which is better that his experimental data (which is 3.0 R). Evidentally, though, these things come out fairly well. I can give other examples in a table as Kauzmann does, and perhaps should.
Now, user:Kbrose has worked to remove all mention of quantum effects in the LEDE of specific heat capacity, saying (in the diff) "quantum theory is not used to predict thermodynamic systems, semiempirical methods are hardly successful." Rather than argue with somebody who does not know what he is talking about (this is not an expression of bad faith, it is a self-evident fact) I'm going to put the matter here and in some chem-group talk pages, and let you all tell him what I just did. Perhaps he'll listen to some of you. S B H arris 00:33, 25 February 2010 (UTC)

Following the example of stable nuclide, I think it's time to modernize both the the isotope and nuclide articles, by putting most of the modern material (including the chart of nuclides) into the nuclide article, which will be the larger one. We can leave a little history in both places, with the full history of the "isotope" name remaining in the isotope article. But the modern term for nuclear species is "nuclide" and isotope is now a subset word which is more specific and refers properly to just the set of nuclides of a given element. So, as the more limited term, it should be the shorter article. Are there any objections if I (mostly) switch this material around? I'm going to leave a similar tag at the isotope article and perhaps at some chem-related wikiproject TALK pages, as well. S B H arris 02:19, 10 March 2010 (UTC)

Methinks that the "Hazards" section should be removed from the infoboxes, because:
Even if that infobox section is deleted, one may still add pointers (under "External links") to the relevant entries in product safety databases. This approach avoids the problems above. In particular, one can have links for multiple countries and/or other types of hazards (environmental, food, etc.); and editors will not feel obliged (or tempted) to add such links to *every* chamical article.

An example of a book cover, taken from Book:Hadronic Matter |
As detailed in last week's Signpost, WikiProject Wikipedia books is undertaking a cleanup all Wikipedia books. Particularly, the {{ saved book}} template has been updated to allow editors to specify the default covers of the books. Title, subtitle, cover-image, and cover-color can all be specified, and an HTML preview of the cover will be generated and shown on the book's page (an example of such a cover is found on the right). Ideally, all books in Category:Book-Class Chemistry articles should have covers.
If you need help with the {{ saved book}} template, or have any questions about books in general, see Help:Books, Wikipedia:Books, and Wikipedia:WikiProject Wikipedia-Books, or ask me on my talk page. Also feel free to join WikiProject Wikipedia-Books, as we need all the help we can get.

I suggest that we try for some consensus on the structure and style of articles on functional groups. July statistics show that these articles are highly consulted (within Chemistry): ether at #23, ester at #28, amine at #39, ketone at #78, carboxylic acid at #121, amide at #141. So to get the conversation going, I (or others if they have inclination) will draft a manual of style within Wikipedia:Manual of Style (chemistry) and then invite other editors to comment. I had started to heavily edit amine and ketone articles, but I will desist until we have some sort of agreement on what these articles should look like.

Hello Pikiwyn. I have observed that you have created a lot of hard-core stubs (e.g. Chlorostyrene; Chloroxuron; Chlorthiamide and so on...) Though it is nice to gain more articles here on Wiki, those stubs are impo not informative. Even the CAS is not listed, what are the substances used for, how can one make them. Many gaps are not close. Just writing e. g. "Chlorthiamide is an organic compound with the chemical formula C7H5Cl2NS." is not sufficiant. On de-Wiki, we would delete them cos they are not anything close to an "article".
First I thought you were a BOT, just pasting some ChemSpider Infos here on Wiki. This is - btw - not good, since on ChemSpider they calculate some physical data. If this is true or not, well, nobody knows. It would be very, very beneficial if you wrote something more about those "organic compounds". Thanks, -- Yikrazuul ( talk) 14:11, 9 August 2009 (UTC)

We ought to revisit the merger of sugar and sucrose. Almost all of sugar is about sucrose, as indicated by the opening paragraph and to the final bit. Parts that are not about sucrose duplicate the content in carbohydrates (saccharide redirects there). So readers are not getting the best presentation, and editors are duplicating effort. I worry also that we are confusing readers. I understand that many editors are wary of merges, but this sugar-carbohydrate-sucrose overlap appears to be a serious disservice. We'd leave carbohydrate alone. Based on the current sizes of the articles, I would propose to shift sucrose content to sugar.--Smokefoot (talk) 13:32, 3 September 2009 (UTC)

Since this is one of the biggest WikiProject, and that a couple of Wikipedia-Books are chemistry related, could this project adopt the book-class? This would really help WikiProject Wikipedia-Books, as the WikiProject Chemistry people can oversee books like Chemistry much better than we could as far as merging, deletion, content, and such are concerned. Eventually there probably will be a "Books for discussion" process, so that would be incorporated in the Article Alerts. I'm placing this here rather than on the template page since several taskforces would be concerned.

I realize that great articles can spring from unpromising starts, but this one is pretty strange. "Optical spectroscopy," which should describes the "color of chemicals" redirects to Spectroscopy. Color could probably use a section that contains a section on "colored chemicals." Or the article on chemical compounds could have a section on their optical properties. My recommendation would be to convert Color of chemicals into an article on aquo complexes, which would feature a list of the colors of the common aquo ions, since that is in the current Color of chemicals. The metal aquo ions (e.g. [Ni(H2O)62+) are important, and we could explain their water exchange properties, pKa's, and possibly roles in everyday life (nutrition, corrosion, catalysis).-- Smokefoot ( talk) 17:05, 13 December 2009 (UTC)
As Smokefoot says, we don't have an article on optical spectroscopy, and UV/VIS spectroscopy describes the measurement technique more than anything else.

Many polymer articles don't have an appropriate infobox. I found one with an inappropriate one too ( sodium polystyrene sulfonate). It will be nice to aggregate information about these polymers in one place. Is it possible to extend the Chembox to have a polymerbox module? Or perhaps a new box which remains consistent with our Chembox? Not being a polymer chemist, I'm not very sure of what data is important, but at the very least, the formula and identifiers should be there. -- Rifleman 82 ( talk) 12:37, 23 December 2009 (UTC)
Could this be a module in the current chembox? The main and the identifiers and properties box seem close enough (add a Tg e.g.), and some others are also appropriate (similar compounds module is useful). -- Beetstra (public) ( Dirk Beetstra T C on public computers) 17:08, 23 December 2009 (UTC)
Yes, would be a good idea. I'm wondering about the MW/formula, though. -- Rifleman 82 ( talk) 17:32, 23 December 2009 (UTC)
Molecular is not a property of a polymer in the terms of the chembox, and the formula can go into the normal field for it. The rest generally should go into ranges, or be omitted as they are often dependent on Mw/Mn (not to speak of, e.g. for polypropyle, tacticity or similar). It needs some creativity, but it can be done. I think it would need a real polymer chemist (not one like me ..) to come up with some things that can't be done now (but if it can't be implemented in the chembox, then a polymer box will have the same problem), but I think our 'biggest' problem is going to be that isotactic polypropylene is not the same as atactic polypropylene which is not the same as syndiotactic polypropylene (e.g. I presume all three have different CASno's?), but that problem already exists for some cis/trans or stereoisomers as well (and the box also is not really capable to solve that problem).

I think that the article "Chemometrics" should start with the etymology of "chemometrics", or alternatively, it should contain a little paragraph devoted to this subject.

The articles poppers and alkyl nitrites had been suggested to be merged here, Wikipedia_talk:WikiProject_Medicine/Archive_17 but then reading an old 2006 talk page discussion, Talk:Alkyl_nitrites an opposite consensus was achieved. I thought getting feedback from this project would be wise on whether poppers and alkyl nitrites should be merged.-- Literaturegeek | T@1k? 07:42, 1 February 2010 (UTC)
This is version 4 (and semester 4) of my graduate class project aimed at improving science content on Wikipedia.

I just now wrote an article on BDTH2, a chelation agent that can be used to separate heavy metals from gold mining effluent and that is also marketed as a dietary supplement to parents of children with autism, and would like some advice about naming and so forth as I don't normally do chemistry articles and I'm sure that I did many things wrong. For starters, this compound seems to have a different name in every source I check: different sources disagree about the IUPAC name. How should this this sort of problem be addressed? What should the article's name be? Any advice would be welcome. Eubulides ( talk) 07:24, 11 February 2010 (UTC)
That some elementary quantum theory is necessary to calculate specific heat capacities from first principles, is an undergraduate textbook subject. For example, my own (dated-- 1966!) copy of W. Kauzmann's Kinetic Theory of Gases, has a full chapter on it. He not only treats the easy cases where the equipartition theory asigns the full R/2 heat capacity per degree of freedom in gases (with a guess as to which degrees will be fully excited and which fully frozen out) but also treats the harder cases in which either rotational or vibrational modes are only partly participating, so that heat capacities are intermediate. Example: chlorine has a Cv heat capacity of 2.5 R if no vibrational modes are exited, and 3.5 R if they all are. The observed value for 25 oC is 3.1 R in modern sources, (2.9 R in the heat capacity article, which needs changing; but 4.1 for Cp = 3.1 Cv in the chlorine article)-- right in the middle of these two equipartitial values. The quantum theoretical value (from Kauzmann) assuming partial excited vibration is 3.1 R, which is better that his experimental data (which is 3.0 R). Evidentally, though, these things come out fairly well. I can give other examples in a table as Kauzmann does, and perhaps should.
Now, user:Kbrose has worked to remove all mention of quantum effects in the LEDE of specific heat capacity, saying (in the diff) "quantum theory is not used to predict thermodynamic systems, semiempirical methods are hardly successful." Rather than argue with somebody who does not know what he is talking about (this is not an expression of bad faith, it is a self-evident fact) I'm going to put the matter here and in some chem-group talk pages, and let you all tell him what I just did. Perhaps he'll listen to some of you. S B H arris 00:33, 25 February 2010 (UTC)
Hello,
does your project cover astrochemistry? Someone at WP:Physics said that astrochemistry is a subfield of astrophysics and thus covered by WP:Physics. It could be covered by both projects, so I'm inquiring here. 70.29.210.242 ( talk) 09:42, 22 February 2010 (UTC)
I was the one who removed the chemistry tag. Feel free to revert me, I just though it was a mistaging based on the name, rather than on the actual content of the field. Headbomb { ταλκ κοντριβς – WP Physics} 21:01, 28 February 2010 (UTC)
WP:ELEMENTS started creating books on each individual elements. Since there are a lot of them, any help would be very much appreciated. Headbomb { ταλκ κοντριβς – WP Physics} 02:33, 28 February 2010 (UTC)
I've butchered Omar M. Yaghi, which wasn't so much an article as a hagiography. A lot of the stuff was taken directly from their website (which bears a copyright sign) so that has all been excised, and a lot of peacock terms have gone. I mention this here because the page has obviously been built and maintained by a member of his research group, and I'm anticipating some arguments! Chris ( talk) 08:42, 28 February 2010 (UTC)
The discussion at Wikipedia:Articles for deletion/Marker degradation may be of interest to members of this project, as it deals with a chemical term that most laypeople are unfamiliar with. Eastmain ( talk • contribs) 23:45, 3 March 2010 (UTC)
I've just created a page on the Faraday Lectureship Prize, but I need some help identifying some of the recipients.
Cheers! Physchim62 (talk) 09:44, 5 March 2010 (UTC)
Can not help with the others at present. More interesting questions are "Who foundered the Prize?" and "Who awarded the early ones"? The Faraday Society did not exist until 1902 and that must have taken over awarding them and then handed it over to the RSC when it merged into that body. I have "The History of the Faraday Society" by Sutton and Davies, but I'm not finding anything about the Prize. However, it does not have an index except for one of names of people. -- Bduke (Discussion) 10:39, 5 March 2010 (UTC)
Following the example of stable nuclide, I think it's time to modernize both the the isotope and nuclide articles, by putting most of the modern material (including the chart of nuclides) into the nuclide article, which will be the larger one. We can leave a little history in both places, with the full history of the "isotope" name remaining in the isotope article. But the modern term for nuclear species is "nuclide" and isotope is now a subset word which is more specific and refers properly to just the set of nuclides of a given element. So, as the more limited term, it should be the shorter article. Are there any objections if I (mostly) switch this material around? I'm going to leave a similar tag at the isotope article and perhaps at some chem-related wikiproject TALK pages, as well. S B H arris 02:19, 10 March 2010 (UTC)
It would be great if some (more) users here would add Commons:Commons talk:WikiProject Chemistry/Categories to their watchlist... and reply the latest section. More discussion topics might follow. -- Leyo 21:33, 12 March 2010 (UTC)

right now before this everybody is discussing about gelatin as solidifying agent and gel producing agent. is any body think that with the addition of other curative medicines we can cure my kind of skin diseases and also it is useful in the way of treating hair fall and problems like curing etching.

Methinks that the "Hazards" section should be removed from the infoboxes, because:
Even if that infobox section is deleted, one may still add pointers (under "External links") to the relevant entries in product safety databases. This approach avoids the problems above. In particular, one can have links for multiple countries and/or other types of hazards (environmental, food, etc.); and editors will not feel obliged (or tempted) to add such links to *every* chamical article. All the best, -- Jorge Stolfi ( talk) 20:49, 22 January 2010 (UTC)
I'd say that the SMILES and INCHI information is actually quite helpful - you can copy it, and paste it into your molecule editor to recreate the same molecule. -- Rifleman 82 ( talk) 02:01, 23 January 2010 (UTC)
are all crystals minerals and if not why ? Thanks Jeff —Preceding unsigned comment added by 74.178.39.147 ( talk) 00:24, 29 January 2010 (UTC)
I do not think that the hazards section should be removed from the chembox. It lists vital information for chemicals which is needed for adequate handling information.-- Cheminterest ( talk) 20:27, 26 March 2010 (UTC)

Template:Chemistry/class and Wikipedia:WikiProject Chemistry. These two pages show different article counts for the different classes. Why? -- Siddhant ( talk) 22:12, 5 March 2010 (UTC)
User:DASHBot/Wikiprojects provides a list, updated daily, of unreferenced living people articles ( BLPs) related to your project. There has been a lot of discussion recently about deleting these unreferenced articles, so it is important that these articles are referenced.
The unreferenced articles related to your project can be found at >>> Wikipedia:WikiProject Chemistry/Archive 19/Unreferenced BLPs<<<
If you do not want this wikiproject to participate, please add your project name to this list.
Thank you.
What is would be the difference of this list compared to the one given below created by a category check] for all article member of Category:All unreferenced BLPs add Category:Chemists?
-- Stone ( talk) 11:06, 28 March 2010 (UTC)
Is it a good idea to make the above list our test if enough people care to work on BLPs? Would be very simple for all people in the project to grab one article from the list find a reference and than strike it in the list. --

An example of a book cover, taken from Book:Hadronic Matter |
As detailed in last week's Signpost, WikiProject Wikipedia books is undertaking a cleanup all Wikipedia books. Particularly, the {{ saved book}} template has been updated to allow editors to specify the default covers of the books. Title, subtitle, cover-image, and cover-color can all be specified, and an HTML preview of the cover will be generated and shown on the book's page (an example of such a cover is found on the right). Ideally, all books in Category:Book-Class Chemistry articles should have covers.
If you need help with the {{ saved book}} template, or have any questions about books in general, see Help:Books, Wikipedia:Books, and Wikipedia:WikiProject Wikipedia-Books, or ask me on my talk page. Also feel free to join WikiProject Wikipedia-Books, as we need all the help we can get.

Even just omitting the blue lines, and making all 'oxygen electrons' blue, and all 'carbon electrons' red would be clearer (which is in line with the drawing of Ben, but then in colour). -- Dirk Beetstra T C 08:55, 1 April 2010 (UTC)
I've asked this question at Talk:Planar chirality#What is the difference between planar chirality and axial chirality?, but I don't imagine that many of you are watching it, so I'll ask here, too.
