    How to write crystal water in the chem template[edit]

    For Tahoka Formation, how do I write the dot between the water and the rest of the formula? Jo-Jo Eumerus (talk) 09:51, 28 February 2024 (UTC)[reply]

    Don't use chem, it has ugly output, instead use chem2. Chem2 converted the * to a centre-dot · . However I prefer to use • as it is more visible. Graeme Bartlett (talk) 10:51, 28 February 2024 (UTC)[reply]

    Split x-ray diffraction from x-ray crystallography[edit]

    I propose splitting X-ray diffraction out of X-ray crystallography, discussion started at Talk:X-ray crystallography#Split x-ray diffraction and crystallography. The two are not the same, and there are many areas of XRD where the focus is not on detailed determination of atomic positions. Examples are powder diffraction where comparison is made to known samples, SAXS and many more. There are many areas/pages where it is relevant to say "use XRD" but wrong to say use "X-ray crystallography This would also help to improve the current rambling X-ray crystallography page. Comments to the X-ray crystallography talk page please. Ldm1954 (talk) 08:40, 14 April 2024 (UTC)[reply]

    Definitions of chemical element[edit]

    Is there a reason the definition of chemical element seems to vary according to the date you look at the article ? Currently it is defined as a monotypical atomic substance, but a few years ago it was the "species of atom with same atomic number" that was used. I wonder why it's not even mentioned in the article now, the Goldbook cited in the introduction gives the two. frwiki, dewiki, itwiki uses the atomic one, if I'm not mistaken.

    The first one seems more complicated and actually a bit dated/historical, the second one is more convenient. The first one is « simple substance Edit this on Wikidata » on Wikidata and there are several wikis that have articles about that. Maybe we should sort the interwikis and move articles to the right item ? TomT0m (talk) 19:26, 22 April 2024 (UTC)[reply]

    Class of DNA/RNA monomer-related structures[edit]

    Nucleobase is the heterocyclic variable group, nucleoside is nucleobase+sugar, nucleotide is nucleotide+phosphate. Is there a term for the parent category containing all of those? I'm working on organizing some synthetic-biology chemical pages, for which we don't have very many of any one of those three but we have some and they do form a coherent topic set. DMacks (talk) 16:39, 1 May 2024 (UTC)[reply]

    Seems like a very worthy project. It looks like we have a full complement of articles on the main natural nucleosides, although some articles might lack a basic ref to a standard biochem textbook. Is there a good online biochem textbook that is not behind a paywall? It would be appropriate to have articles for each of the main natural nucleotide monophosphates (and eventually all of the diphosphates and triphosphates). I am trying to think of what core info we might want for these articles because otherwise their physical properties are probably comparable and unremarkable. Maybe their tautomers (for the nucleobase articles), base-pairing partners, their susceptibility to modification (N- or O-methylation as in epigenetics). Good luck. --Smokefoot (talk) 16:18, 2 May 2024 (UTC)[reply]

    Coverage of chemistry competitions for school pupils[edit]

    I am asking for the support of this community to move the following page from drafts to articles: https://en.wikipedia.org/wiki/Draft_talk:Baltic_Chemistry_Olympiad. That will help with increasing the coverage of chemistry competitions.

    Wikipedia covers several major competitions, such as the International Chemistry Olympiad and USNCO. However, there should be more pages to raise awareness. I have written a detailed overview of the Baltic Chemistry Olympiad and Competitions. It is one of the oldest international competitions, which over 30 years generated over 180 problems for training students and popularising chemistry.

    Wikipedia:Articles for deletion/Baltic Chemistry Olympiad was why it was deleted. Graeme Bartlett (talk) 10:30, 11 May 2024 (UTC)[reply]

    Ninovium[edit]

    I just found ninovium article. I think this article should either be merged with Victor Ninov or with oganesson. Could somebody please take a look? ReyHahn (talk) 13:26, 15 May 2024 (UTC)[reply]
