United entry template for the isotope lists

Once I'm finished updating all of the isotope tables, I had the idea of creating a unified template to codify the table entries. It would uniformize the tables in a format that is easier to edit, and would allow extended capabilities such as sorting for the half-life table (using converted value in a common unit, as explained in this MOS talk). –LaundryPizza03 (d c̄) 02:16, 7 January 2025 (UTC)[reply]

Sorting the half-lives is possible, but the list will be weird because the rows will be split. For example, a nuclide with 3 decay modes will be split into 3 rows after sorting the half-lives. Nucleus hydro elemon (talk) 11:49, 10 January 2025 (UTC)[reply]

Should be OK: for nuclides with multiple decay modes, each decay mode is allocated the nuclide's half-life, rather than the decay mode's partial half-life. E.g. see Isotopes of helium. Preimage (talk) 13:18, 10 January 2025 (UTC)[reply]

Incorrect spectral lines

At Wikipedia_talk:WikiProject_Chemistry#Radon_and_Radium_spectral_lines it was discovere that all of the spectral lines in elements articles are poorly sourced and wrong. They recommended creating fresh new images from the NIST Atomic Spectra database, and replacing across all wikis. –LaundryPizza03 (d c̄) 01:56, 14 January 2025 (UTC)[reply]

Glow from curium sample

File:Curium self-glow radiation.jpg is described as "Curium metal glowing. The radiation from curium is so strong that the metal glows purple in the dark." Metal glowing purple seems unusual from a blackbody standpoint, but obviously radiation might not be simple thermal effects. However, I see the metal and I see the glow, but the glow seems to be the region around the metal. The front is decidedly darker than the edges and even (to my eye) just beyond the edges, as if it's the air glowing not the metal. Is the given description actually correct? DMacks (talk) 03:06, 11 February 2025 (UTC)[reply]

Curium is a very strong alpha particle emitter; so maybe ionized-air glow. This paper has an image of radioluminescence that looks similar: Alpha Particle Detection Using Alpha-Induced Air Radioluminescence Johnjbarton (talk) 03:34, 11 February 2025 (UTC)[reply]

That makes a lot more sense. Thanks for finding the refs and links, and adjusting the article's caption. DMacks (talk) 14:53, 13 February 2025 (UTC)[reply]

Typos in isotope lists

@LaundryPizza03: I see you recently updated the isotope lists, a new editor @Michel Béliveau: has found some typos in them and asked about them at Commons:Commons:Help desk#Modifications to the "List of Isotopes" pages, examples are

Z = 22 Isotopes of titanium Ti50 49.944785.622 Error = 2 decimal points Correction : 49.944785622

Z = 38 Isotopes of strontium Sr105 10495900 Error = No decimal point Correction : 104.95900

Z = 45 Isotopes of rhodium Rh96 95914452 Error = No decimal point Correction : 95.914452

Z = 52 Isotopes of tellurium Te123 122,9042710 Error = "," instead of "." Correction : 122.9042710

Z = 54 Isotopes of xenon Xe136 135907214.474 Error = Misplaced "." Correction : 135.5907214474

Z = 73 Isotopes of tantalum Ta156 15597209 Error = No decimal point Correction : 155.97209

What would be the best way for them to report this kind of error. TSventon (talk) 05:00, 19 February 2025 (UTC)[reply]

@TSventon: This page is a great place; pinging a particular editor is helpful, but there are several page watchers here who are willing to help. I’ll leave this one to @LaundryPizza03 since he’s been editing over there, but if he doesn’t get back to you, ping me and I’ll have a look. YBG (talk) 05:57, 19 February 2025 (UTC)[reply]

I pinged LaundryPizza03 because they did the update, I am not implying that they are responsible for all the errors. I have checked the above suggestions, linked the articles, and the suggestions appear to be correct. TSventon (talk) 06:31, 19 February 2025 (UTC)[reply]

Michel Béliveau thank you for checking the articles and suggesting corrections. I have posted the 6 corrections you suggested. Please could you report your remaining corrections on this page? TSventon (talk) 19:34, 20 February 2025 (UTC)[reply]

Hello.

Thank you for applying the previous corrections.

Here is another simple correction :

For Z = 72 Element = Hafnium Isotope = ¹⁷⁹Hf Natural abundance = 179.xxx is incorrect ; should be between 0 and 1.

In the "Main Isotopes" table ( at the top of the page, ) it is specified as 13.6 %

I do not know the correct value but 0.136 would be a better value.

All other corrections are a bit more complex. Here is one of many (more than 20 ) about decays :

For Z = 13 Element = Aluminum Isotope = ³⁷Al with Decay Mode = β⁻ 2n Specified result = ³⁶Si My correction : ³⁵Si

If you agree with this correction, I could send the rest ( all together or by groups of say 5 or 6 at the time)

That kind of correction is precisely why I wished to have confirmation by Wikipedia. Michel Béliveau (talk) 20:30, 20 February 2025 (UTC)[reply]

I don't normally edit in this area, so I don't want to make corrections which involve an understanding of the material. I would suggest groups of corrections, linking to the article to be corrected and giving each correction a number like D1 for the first decay correction. It could take some time, depending on how busy the editors here are. Is your information sourced to NUBASE2020?

I looked at Isotopes of hafnium and 179.9465595 appears to be an isotopic mass, not a natural abundance. TSventon (talk) 21:17, 20 February 2025 (UTC)[reply]

I had noticed the same thing about ¹⁷⁹Hf.

Concerning NUBASE2020, my information is based from your own "Lists of Isotopes" pages that I downloaded from Wikipedia.org using the "Curl" function. You refer very often to NUBASE2020, not me.

I will modify my program to produce the Decay corrections in the format I used ( along with the Dxx number ) and send them by groups of 5 at the time ) I know that verifying each correction will take some time...

First group will be send tomorrow. (To you so you would pass it to the correct group ? )

I also think that I am using an important portion of your time. So thank you very much. Michel Béliveau (talk) 22:22, 20 February 2025 (UTC)[reply]

Thank you, please could you post corrections on this page? Otherwise I would have to copy them here. The Hafnium figure seems to be entered in the article table as an isotopic mass, so if it has been imported to your database as a natural abundance it does not mean the article is incorrect. It could be that different article tables are formatted differently and that confuses the curl function. I have looked at several article histories and the edits which add the figures you are querying all credit NUBASE2020, I hadn't heard of it previously. Aso, could you include today's queries in your batches as that will make it easier to track them. TSventon (talk) 22:56, 20 February 2025 (UTC)[reply]

Is this what you had in mind ?

D1 Article = https://en.wikipedia.org/wiki/Isotopes_of_aluminum

Isotope : ³⁷Al Decay mode : β⁻ 2n Result specified : ³⁶Si Should be : ³⁵Si

D2 Article = https://en.wikipedia.org/wiki/Isotopes_of_potassium

Isotope : ⁵⁵K Decay mode : β⁻ 2n Result specified : ⁵⁴Ca Should be : ⁵³Ca

D3 Article = https://en.wikipedia.org/wiki/Isotopes_of_vanadium

Modifications to the "List of Isotopes" pages

I was told to use the "Curl" function with your "List of isotopes" pages to update a personnal database about Isotopes and decays. This is great : I can now regenerate my database in less then 15 minutes compared to around 10 days to do the same thing manually.

However, I found some cases that need some attention ( I already applied corrections in my previous personal database

27 cases for which I have a correction 58 cases for which I have a small modification to your "List of isotopes" pages 19 cases for which an invalid numeric data was specified

Can I submit these cases to somebody at Wikipedia ?

Thank you very much. Michel Béliveau (talk) 21:04, 17 February 2025 (UTC)[reply]

Michel Béliveau, the help page and teahouse at en Wikipedia are currently protected due to vandalism, which means you need to have ten edits on en Wikipedia and an account at least 4 days old to post there. Currently you only have five, but your account is old enough. Can you ask me this question on your talk page 1 edit, add some examples of what you want to do in 4 edits, then you should be able to post on the tea house or help desk. You need to provide sources for any corrections you are requesting. Normally we don't encourage "gaming" permissions (en:WP:PGAME), but I think it is reasonable in this case. TSventon (talk) 22:05, 17 February 2025 (UTC)[reply]

Good day.

I am not sure I understood what you meant. I had prepared documents to send by email but it looks this is not the way to proceed at Wikipedia.

Here are some easy corrections :

Z = 22 Titanium Ti50 49.944785.622 Error = 2 decimal points Correction : 49.944785622

Z = 38 Strontium Sr105 10495900 Error = No decimal point Correction : 104.95900

Z = 45 Rhodium Rh96 95914452 Error = No decimal point Correction : 95.914452

Z = 52 Tellurium Te123 122,9042710 Error = "," instead of "." Correction : 122.9042710

Z = 54 Xenon Xe136 135907214.474 Error = Misplaced "." Correction : 135.5907214474

Z = 73 Tantalum Ta156 15597209 Error = No decimal point Correction : 155.97209

Detection by my application

Correction by me ...

Here is one of 21 important corrections. ( These are why I asked Wikipedia to confirm ).

Z = 13 Aluminium Al37 Decay mode = β⁻ 2n Decay result specified = Si36 Decay result expected = Si35

Detected by my application

Correction provided by my application

Michel Béliveau, I have asked about this at en:Wikipedia talk:WikiProject Elements, you should be able to post there. TSventon (talk) 05:06, 19 February 2025 (UTC)[reply]

Why are hardness attributes in MPa?

Is there a reason hardness units have been converted from their native units (such as BHN for Brinell Hardness) to MPa? As an engineer I have to convert these units back to apply them, and I do not know if I am using the same conversion formula as the page authors (as hardness often does not correlate cleanly to pressure). Is using native units no longer the common practice? Would anyone mind if native units were provided alongside the MPa values? TTK (talk) 19:29, 20 February 2025 (UTC)[reply]
