Hello. I note that you have extensively corrected the information on numbers of isotopes of each element in the article Isotope, and that you have left unchanged the statement that "27 mononuclidic elements have only a single stable isotope". Could you also look at the article Mononuclidic element which seems to say that there are 19 (plus 3 with one very long-lived isotope). Which of the two articles is correct please?
If somehow the difference in wording means that both are correct, then I think the difference needs further explanation. Dirac66 ( talk) 18:34, 14 January 2009 (UTC)

The Commission on Atomic Weights and Isotopic Abundances (CAWIA) of IUPAC defines an element as monoisotopic "if it has one and only one isotope that is either stable or has a half-life greater than 1×1010 a" (see [1], p. 708, where also the list is presented: "The following 21 elements are considered to be monoisotopic in the evaluation of the atomic weights: Be, F, Na, Al, P, Sc, Mn, Co, As, Y, Nb, Rh, I, Cs, Pr, Tb, Ho, Tm, Au, Bi, and Th."). Thus, vanadium, rubidium, indium, lanthanum, europium, lutetium and rhenium should be removed from the list, and bismuth should be add. The radioactivity of several nuclides of these elements has nothing to deal with their natural occurrence. -- V1adis1av ( talk) 13:32, 31 March 2011 (UTC)
So I'll do two things: 1) remove one nuclide from the mononuclidic list (Pa-231 unless NIST defends it strongly), 2) add the IUPAC reference you found above and note that IUPAC sometimes uses "monoisotopic" when they mean the more-specific word "mononuclidic" and that "monoisotopic" thus has TWO non-compatable definitions in use, out in the community.

Прочитал твою (на русской ВП сам просишь, если что, всегда можно на "Вы") критику к моим замечаниям в статье о натуральном прометии. Вообще-то, я несогласен, хотя у меня есть смутное ощущение, что кандидат может понимать немножко лучше меня в своем профиле :) Надеюсь, дальнейшая дискуссия пойдет дружелюбно, я никого учить не собираюсь, а лишь надеюсь во всем разобраться при помощи профессионала. ОК?
Итак. Тα/Тβ≈3,6×108. Верно? Логаримф по основанию два от этого числа равен примерно 28,4. Другими словами, за то время, что альфа-распадется 1 атом (после 1 периода полураспада, как округление модели), бета-распадется 228,4 (≈350 000 000) атомов. То есть, если у нас найдется примерно 350 млн атомов прометия-145, один из них распадется альфа-распадом. На 1 моль (6×1023 атомов) найдется 1015 таких атомов. А лютеция, между прочим, 2 кг в год делают, а сколько его спрятано еще... :) То есть предпосылки, по моему мнению, вполне есть. Хотя это и против здравого смысла (меня тоже смутило). Может, я в чем-то ошибся? С удовольствием выслушаю критику :)
Могу (позже) попробовать придраться к тому, что написал ты, только не сейчас, но вообще готов попробовать. (По-моему, такая странность кроется в том, что это математический закон, экстраполированный на реальную жизнь с ограничением на исключительно целые числа атомов...имей мы возможность дискутировать о наличии 0,01 атома, таких странностей бы не было)
Да, и вот еще. Хотя 1966 год и правда уже дряхловат, логика же не поддается времени, только точность измерений (ясен пень, улучшается, чем дальше живем). Плюс я не нашел того, что ты утвержадешь в книге (ни единого слова "бета"). Можно мне номер страницы или (а лучше - и) цитату? Даже если я и не прав, этот факт тожде можно было бы включить :)

Да, и вот еще. Хотя 1966 год и правда уже дряхловат, логика же не поддается времени, только точность измерений (ясен пень, улучшается, чем дальше живем). Плюс я не нашел того, что ты утвержадешь в книге (ни единого слова "бета"). Можно мне номер страницы или (а лучше - и) цитату? Даже если я и не прав, этот факт тожде можно было бы включить :)
Надеюсь, мы сможем мирно продолжить дискуссию здесь и по-русски. Just in case, if you got anything against, we may switch back English and go back to the original talkpage. OK?-- R8R Gtrs ( talk) 16:21, 17 February 2012 (UTC)

I moved the Russian list to User:V1adis1av/List of Taras Shevchenko National University of Kyiv people/Russian list; we typically stash this sort of thing in user space so they don't show up on search engines and the like. Regards! VQuakr ( talk) 07:41, 12 September 2013 (UTC)

Hello Books & Bytes subscribers. There is a new Visual Editor reference feature in development called Citoid. It is designed to "auto-fill" references using a URL or DOI. We would really appreciate you testing whether TWL partners' references work in Citoid. Sharing your results will help the developers fix bugs and improve the system. If you have a few minutes, please visit the testing page for simple instructions on how to try this new tool. Regards, MediaWiki message delivery ( talk) 18:48, 10 April 2015 (UTC)

Hi. Thank you for your recent edits. Wikipedia appreciates your help. We noticed though that when you edited Hypercharge, you added a link pointing to the disambiguation page Charge. Such links are almost always unintended, since a disambiguation page is merely a list of "Did you mean..." article titles. Read the FAQ • Join us at the DPL WikiProject.

Thank you for filling out the history and fate of the small steam-powered icebreaker Silatch/Ilmarinen. I made a technical request to move the article under the ship's original/final name Silatch which is now a redirect; I can do the necessary copyediting to article lead etc. once this is done.

Hi. Thank you for your recent edits. An automated process has detected that when you recently edited Cape Prince of Wales, you added a link pointing to the disambiguation page Yupik. Such links are usually incorrect, since a disambiguation page is merely a list of unrelated topics with similar titles. (Read the FAQ • Join us at the DPL WikiProject.)
