When to use chemical symbols and when *not* to.

The article seems not to contain any guidelines for when to write say "triuranium octoxide" vs "U3O8" with the numbers as subscripts, of course. Mentioning "U3O8" is also very different from using it. Likewise, when should one write, if ever, "triuranium-235 octoxide" rather than using a chemical formula including a nuclide symbol? Readers need to know this, especially if they are editing Wikipedia.

I just posted a long comment about a similar issue about nuclide symbols, so for more info that more or less applies also to my question here, please have a look at that. Here's the link: https://en.wikipedia.org/wiki/Talk:Nuclear_weapon_design#235U_versus_uranium-235. Polar Apposite (talk) 17:17, 18 August 2023 (UTC)

Atomic symbol

Why is there no mention of the fact that IUPAC, the official arbiter of chemical terminology, uses the term atomic symbol rather than "chemical symbol" or "element symbol"? See https://goldbook.iupac.org/terms/view/A00503. Samer (talk) 02:29, 24 August 2023 (UTC)

Systematic

In the section on obsolete symbols: to reduce clutter, i moved the systematic chemical symbols into a new subsection, “Systematic chemical symbols”. Okay? Should the title of said new section be shortened to “Systematic symbols”? I added, “When elements beyond oganesson (starting with ununennium, Uue, element 119), are discovered; their systematic name and symbol will presumably be superseded by a trivial name and symbol.” Should a source be cited for said factoid? If so, perhaps a source could be found among the sources cited by the article “Ununennium”?

Also, in the list of symbols no longer in use, i was thinking of also separating out the symbols for Mendeleev's predicted elements, into another separate subsection, or at least a separate list. Should i do that? Solomonfromfinland (talk) 04:22, 10 April 2024 (UTC)
