Template:NUBASE2020

The article on Erbium the section on Isotopes uses NUBASE2020 as its sole reference. Then it makes statements like:

Naturally occurring erbium is composed of 6 stable isotopes...

However, the NUBASE reference contains nothing but tables of isotope properties. It seems to me that we could cite the table for facts about specific isotopes, but nothing about the collection of them. That is, the entire isotopes section is original research based on analyzing the tables. Since this is a template reference it seem like the use may be widespread. What do you think? Johnjbarton (talk) 16:21, 9 July 2024 (UTC)[reply]

NUBASE includes detailed decay data, and for primordial isotopes, gives their fraction of natural abundance. Indeed it is widely used as a reference, though in exactly the same context (citing isotope data), and pages that contain data more recent than 2020 or describe applications or properties in detail have additional reference. I wouldn't say that identifying precisely six primordial (and stable, as it happens) erbium isotopes from the table, given that they have abundance fractions, is WP:OR; arguably it's simple counting as permitted under WP:CALC. However, if you feel that adding additional sources would be helpful, feel free to do so. ^Complex/_Rational 17:40, 9 July 2024 (UTC)[reply]

Cropping gas discharge tube images

I cropped a few of the gas discharge tube images to make it more clear which part was the noble gas (specifically krypton, argon, and xenon are currently cropped) but this has been contested by @Zzzs (pinging here), so I'm putting up a talk page section.

Why I cropped the images: With the strong colors from both parts of the tube it's hard to tell which part is the gas; cropping it makes it obvious and makes it easier to compare them. It also makes the images less overly wide, which is good generally. Mostly it makes the image dominated by the important color. I reverted hydrogen because that one doesn't have very strong colors not coming from the gas, so it doesn't really need it, but I think the other ones do.

They are featured pictures, but it's still a featured picture if you crop to the important bit for ease of understanding & comparison. Mrfoogles (talk) 18:49, 19 July 2024 (UTC)[reply]

Good article reassessment for Zirconium

Zirconium has been nominated for a good article reassessment. If you are interested in the discussion, please participate by adding your comments to the reassessment page. If concerns are not addressed during the review period, the good article status may be removed from the article. Z1720 (talk) 00:14, 23 July 2024 (UTC)[reply]

RfC: On discovery of the 23 nonmetals

Should this content on the discovery of the 23 nonmetals be removed from the nonmetal article?

RfC is here. --- Sandbh (talk) 13:37, 23 July 2024 (UTC)[reply]

Neptunium

The infobox image for neptunium was recently replaced by File:Neptunium_metal.jpg because the old image didn't show the pure metal. It will need to be reassessed for Wikipedia:WikiProject_Elements/Pictures. –LaundryPizza03 (d c̄) 00:47, 4 August 2024 (UTC)[reply]

Probably it should be a C, given the low resolution. But it's likely difficult to find anything better. Double sharp (talk) 06:01, 4 August 2024 (UTC)[reply]

The infobox image for plutonium is being discussed at Template talk:Infobox plutonium#Infobox image and may be changed to File:Plutonium ring.jpg, so it may need reassessment too. HertzDonuts (talk) 17:44, 4 August 2024 (UTC)[reply]

"the"

@Grendon84 has been systematically changing the first part of elements like:

Selenium is a chemical element; it has the symbol Se and atomic number 34.

to remove "the":

Selenium is a chemical element; it has symbol Se and atomic number 34.

The edits are marked minor and have no edit summary.

If there is an agreed form this it should be cited in the change. If not these changes should not be made, they are just annoying and to me they read like a word is missing. Johnjbarton (talk) 16:57, 9 August 2024 (UTC)[reply]

To my understanding, the form without "the" was initially approved, though I prefer using "the" as it reads as a bit more natural. 108.160.120.147 (talk) 13:13, 11 August 2024 (UTC)[reply]

Paper accepted for publication that updates various nuclei

While cleaning Isotopes of silver (updated to NUBASE2020 in 2022), I uncovered a paper, which has been accepted to Physical Review C and is available as an arXiv preprint, that updates the masses of various nuclei.

C.; Suhonen, J.; Vilen, M.; Virtanen, V.; Zadvornaya, A. "Physical Review C - Accepted Paper: Isomeric states of fission fragments explored via Penning trap mass spectrometry at IGISOL". journals.aps.org. arXiv:2403.04710.

This updates the following nuclei and their isomers: ⁸⁴Br, ¹⁰⁵Mo, ¹¹⁵Pd, ¹¹⁹Pd, ¹²¹Pd, ¹²²Ag, ¹²⁷In, ¹²⁹In, and ¹³²Sb. In particular, I have updated ¹²²Ag in the table — for this nucleus, the 3− state in NUBASE2020 is declared nonexistent. –LaundryPizza03 (d c̄) 07:05, 2 September 2024 (UTC)[reply]
