Deuterium section has mildly inaccurate information

Under Properties : Compound : 2H : currently reads... "All deuterium in the universe is thought to have been produced at the time of the Big Bang, and has endured since that time." (as of 1418 EST on 12July2023)

I believe it should read: "Nearly all naturally occurring deuterium in the universe..." When people talk about the emissions from nuclear power plants they sometimes mention the isotopes of hydrogen that we generate and release to the public, which can include deuterium.

I generated a talk section instead of editing because I don't know the appropriate formatting. Here's hoping a more senior user can fix it!

Thanks! 216.99.180.228 (talk) 18:24, 12 July 2023 (UTC)

Done. Thanks for your suggestion. Clayoquot (talk | contribs) 01:56, 26 October 2023 (UTC)

Tritium glow

What does tritium glow like in a tube like those shown for hydrogen and deuterium? Is it similar to deuterium? 2603:6000:8740:54B1:98C0:1879:4C99:365D (talk) 21:32, 30 August 2023 (UTC)

Tritium doesn't glow. What you see in applications such as gun sights, is a phosphor coating on the inside of the glass that is being excited by beta particle emissions from the tritium and releasing photons. 57.135.233.22 (talk) 05:57, 3 November 2023 (UTC)

Misleading text in paragraph under "combustion"

In this paragraph, Hydrogen is not explosive and totally safe to be consumed as it can also be used to change ur pitch as a fun joke to play on your kids 99.6.61.222 (talk) 00:40, 23 October 2023 (UTC)

I removed. "The explosive reactions may be triggered by spark, heat, or sunlight.", which was unsourced. Thanks for pointing this out! Clayoquot (talk | contribs) 01:50, 26 October 2023 (UTC)

Thank you! And you're very welcome! 99.6.61.222 (talk) 15:15, 26 October 2023 (UTC)

Hi Moriarty49. Welcome! Clayoquot (talk | contribs) 23:00, 25 October 2023 (UTC)

Welcome. If you're granted access, please consider taking care of the issue I mentioned days ago right above your post. Sunlight does not ignite a hydrogen and oxygen (or air) mixture. The current editors don't seem to be interested in fixing this. 99.6.61.222 (talk) 00:29, 26 October 2023 (UTC)

I apologize for being slow on this. Addressing it now. Clayoquot (talk | contribs) 01:48, 26 October 2023 (UTC)

WP:URFA/2020

I am reviewing this very old FA as part of WP:URFA/2020, an effort to determine whether old featured articles still meet the featured article criteria. Last reviewed in 2008, there is considerable uncited text, the "Phases" section is only a list, Niche and evolving uses is a list, there is some overquoting, the See also section needs attention, and there may be more. Listing at WP:FARGIVEN. SandyGeorgia (Talk) 18:06, 1 November 2023 (UTC)

Thanks for reviewing this Sandy. This strikes me as a very difficult topic to bring to FA standards. I can't think of any article that spans as much of the Dewey Decimal System and as many university textbooks as this one does. It's an important topic in basic science of course, and also an important part of the conversation around climate change mitigation, which is in the realm of technology and economics. In addition to the points you raised, there is also some repetition, excessive detail/trivia, and breaking news.

Part of the reason for repetition is that the climate change story is not well-integrated and solving that would require some pretty deep structural reworking. I could probably improve some things from a climate change perspective but to make the necessary progress we'd also need to have at least one experienced chemistry editor give it some dedicated work. Any volunteers? Clayoquot (talk | contribs) 00:33, 7 November 2023 (UTC)

What are your thoughts making up in your mind about restoring the version done by Grendon84 newly to the original one?

I had sought a matter concerning about the change of factual content in this article, exactly he made two edits in total, include the removal of the subject 'it' (more detail in the page history), and rechange to the word 'with', which the editor named Turnbull has pointed it out. Are you seeing that consistent? And whom of you are keen to edit or fix some wording? I'd love to hear from you as soon as before I turn offline. Thanks, you are welcome to response my idea. 2001:EE0:4BC7:CC30:B58E:E5C:90B0:54BE (talk) 12:34, 20 November 2023 (UTC)

In my perspective, I'm not in favor of that change. If anyone makes up an opinion, feel free to let me know. 2001:EE0:4BC7:CC30:B58E:E5C:90B0:54BE (talk) 12:35, 20 November 2023 (UTC)

I like ... chemical element; it has symbol better than ... chemical element with symbol. I looked at like twenty other element articles and they all start with the format of the first sentence ("it has"). Not a big deal, but prefer the previous verion. Folly Mox (talk) 13:16, 20 November 2023 (UTC)

See Misplaced Pages talk:WikiProject Elements#"a" chemical_element or "the" chemical element - ... chemical element; it has symbol was the outcome of the discussion. Pr {contribs} 17:59, 20 November 2023 (UTC)

There was a considerable discussion and eventual consensus to use the "; it has" version. Changes should follow WP:BRD. Bazza (talk) 18:58, 20 November 2023 (UTC)

Hello, may you put heading infomation to notify the readers we are looking through the article about a chemical element?

Should there be any way to make a notification that we are currently reading the article about a chemical element? Thanks and I'm seeking for response. 2001:EE0:4BC4:5DC0:74A5:B633:51B2:265D (talk) 11:44, 26 November 2023 (UTC)

This is already done in the very first five words of the article – what do you want changed? Tollens (talk) 11:48, 26 November 2023 (UTC)

Don't you know the hatnote? 2001:EE0:4BC4:8D40:65D1:E41F:7E97:C466 (talk) 13:07, 15 December 2023 (UTC)

Ah – from your original request it appeared you wanted the information to be placed in the prose of the article.  Done Tollens (talk) 17:52, 15 December 2023 (UTC)

I don't think hydrogen was coined in 1783 by Lavoisier

Exactly as the title says, the citation for that claim doesn't even mention Lavoisier, and after searching around I found a source which claims Lavoisier's writings didn't refer to "inflammable air" as hydrogen for all of 1784 (https://gwern.net/doc/history/1851-wilson-thelifeofthehonhenrycavendish.pdf pages 151-152) and another source which pegs the earliest usage of hydrogen as 1787 in Méthode de nomenclature chimie (https://link.springer.com/article/10.1007/s10698-022-09448-5) by Morveau et al. This source also claims to have not found an instance of the term "hydrogen" in Lavoisier's work before 1787.

Given the language of the original source using "we", I also think it's very possible that Lavoisier shouldn't receive full credit and it may be shared with Morveau, although it's hard to confirm as I do not speak French. 2600:1011:A105:25D:4957:979:9E7:4BA8 (talk) 10:41, 22 December 2023 (UTC)

For what it's worth, the 1783 date was added to the article back in 2006 by the late editor Sbharris. gobonobo 10:50, 22 December 2023 (UTC)

I raised the question at the Reference Desk and am just going to copy the response here:

The French Misplaced Pages has an article on the treatise Méthode de nomenclature chimique by Morveau and others, published in 1787. The etymology section for hydrogène of the TLFi only mentions the 1787 treatise. While this may have been the first publication using the term hydrogène, Lavoisier praises Morveau in the introduction of this treatise for his major role in designing the new nomenclature. Morveau himself uses the spelling Hidrogène. Since he explicitly credits Lavoisier for the name oxygène, it is unlikely the name hydrogène is due to specifically Lavoisier. Morveau acknowledges the role of unnamed members of the Académie, as does Lavoisier in the introduction. Morveau published a treatise on the nomenclature in 1782; it would be interesting to see which name he proposed there for "the base of inflammable air".  --Lambiam 19:32, 24 December 2023 (UTC)

If the first instance of hydrogène in print was the Méthode de nomenclature chimique, we should change the 1783 date. Note that Méthode had four authors: Morveau, Lavoisier, Claude Louis Berthollet, and Antoine François Fourcroy. Based on the sources above, I suggest we change the article to indicate that the naming occurred by 1787 and attribute the coinage to the document rather than to Lavoisier. gobonobo 16:46, 25 December 2023 (UTC)

I have an opinion that we should modify the lead sentence to be more a bit constructive.

I have come up with the suggestion to change some detail like: It is the lightest element, and at normal temperature, is a gas with the formula H₂. Best moving to: It is the lightest element on Earth. At normal temperture, this element is a gas with the formula H₂. Any thoughts? 2001:EE0:4BC4:9510:65D1:E41F:7E97:C466 (talk) 14:27, 25 December 2023 (UTC)
