Seems like an error

[edit]

I changed from {{ComplexNuclide2|Helium|4}} to {{Nuclide2|Helium|4}} in Helium-4 because it generated

4 He
2 2

and not the

4 He
2

that I think is more appropriate. Is this an error or a misuse of the template? ... said: Rursus (mbork³) 12:20, 27 October 2009 (UTC)[reply]

This is not the place to ask that question: this talk page is for questions about the template itself and not for questions about the pages that use it. Please ask suchs question on the appropriate page, in this case the Talk:helium-4 page.     — SkyLined (talk) 17:26, 2 November 2009 (UTC)[reply]

what is that suffixed subscript?

[edit]

See Talk:Chemical_formula#Subscript_ambiguity: where is this notion defined? - DePiep (talk) 03:37, 7 August 2018 (UTC)[reply]

I believe I created that based on existing MathML examples found in pages at the time. That unfortunately means I do not know why it's there, not do I have references to it's official definition. SkyLined (talk) 06:27, 7 August 2018 (UTC)[reply]
I wanted to find the originally pages that I implemented these templates for, which IIRC were all about nuclear reactions in stars. I thought there was a link where you can see which pages use a specific template, but I cannot find it. I tried to manually find an example of a page using ComplexNuclide2 but was unable to. For all I know this template is not used anywhere. I looked at the code to see if I left some documentation to explain it, but it looks as if the suffixed subscript at the bottom right is simply a copy-paste of the prefix subscript at the bottom left. This may actually simply be a mistake I made in the original that has survived for 15 years. SkyLined (talk) 08:54, 7 August 2018 (UTC)[reply]
That list youwere looking for is under the "What links here" tool. this are the arcicles, today (3). Please take a look at the discussion in the link I gave (continue there please). - DePiep (talk) 14:51, 7 August 2018 (UTC)[reply]
Thanks. This template does not appear to be used much at the moment, but I did find out what it is: the suffixed subscript is used for the number of neutrons. It's is convenient if you dislike having to subtract the number of protons (bottom-left) from the mass number (top-left).
I'm not going to debate this myself, as I have no opinion on the matter. All I can say is that I created it 15 years ago based on what I remembered from highschool physics and existing nuclide symbols in various Wikipedia pages at the time without having an external reference.

Thanx anyway. The discussion in the other thread is: is this way of writing commonly used in science? Also, it is confusing because that same position is used for the number of element atoms in regular chemical formulae. -DePiep (talk) 16:05, 7 August 2018 (UTC)[reply]
No problem. I read the discussion but since I have no new information or solution to offer, I am not going to add noise there. SkyLined (talk) 20:04, 7 August 2018 (UTC)[reply]

neutrons

[edit]

In some nuclear reaction equations, it is nice to have a neutron (n) with Z and A sub/superscripts. It seems that this template would be the best one, but it doesn't have the option, that I can see, to do it. Would it be possible to add? Since {{ProtonsForElement}} doesn't know neutron, that complicates it. Gah4 (talk) 11:17, 19 October 2021 (UTC)[reply]

Could you link to examples/articles? thx. -DePiep (talk) 11:38, 19 October 2021 (UTC)[reply]
The one I was editing is: Plutonium-238#History. It is nice to look at both sides, and see that Z and A balance. I suppose next is going to be one for electron, and for positron, but I didn't ask that yesterday. One could look through articles using {{ComplexNuclide2}} and see how it is used. Gah4 (talk) 18:52, 19 October 2021 (UTC)[reply]
Good example, I can understand & support the 'visual balance' expectation (thumb up emotion here). So there should be an option like
238
92
U
... = ... 2n      [demo1]
or better? -DePiep (talk) 21:11, 19 October 2021 (UTC)[reply]
More like: 2 1
0

Also, Chart of the nuclides traditionally has n for Z=0, N=1.

AFAIK There's no standard way of writing nuclides that displays the number of neutrons. Do you have an example outside of Wikipedia where this is done? (By definition, Wikipedia cannot create its own standards, so we need an external source) SkyLined (talk) 20:33, 19 October 2021 (UTC)[reply]

I don't know of any. If you balance A and Z, N also balances. Otherwise people are expected to subtract.
