Result: Procedural close. @Ldm1954: this article needs a featured article review, not a good article reassessment. See WP:FAR for instructions. Queen of Hearts (talk) 22:26, 6 September 2024 (UTC)

During checking the sources a month ago, I found 14 that failed verification. This ranged from truncated quotes to inappropriate use of sources to support points that they don't make. At about the same time Johnjbarton (talk · contribs) also found a significant number of errors and irrelevant information; everything can be found in the edit history or in main page tags. As such it fails GA 2b, 3b, 4 and perhaps others. I posted on the talk page that I was considering a GAR, and the original FA nominator responded with comments that violate the fourth pillar of Wikipedia. Until these major issues are resolved not only does it not merit FA status, it does not merit GA. Ldm1954 (talk) 21:15, 6 September 2024 (UTC)

Requested move 19 November 2024

The following is a closed discussion of a requested move. Please do not modify it. Subsequent comments should be made in a new section on the talk page. Editors desiring to contest the closing decision should consider a move review after discussing it on the closer's talk page. No further edits should be made to this discussion.

The result of the move request was: moved to Heavy metals. It appears to me that consensus eventually did form around the later proposition. (closed by non-admin page mover) Bobby Cohn (talk) 21:04, 3 December 2024 (UTC)

Heavy metal element → Heavy metal (chemistry) – This article has been moved many places over the years with various attempts at disambiguation with other topics listed at heavy metal. While the current WP:NATURAL disambiguation has merit, it is not consistent with similarly titled articles like light metal, trace metal, toxic heavy metal, transition metal, precious metal, base metal, noble metal, native metal, etc. So I think we need to bite the bullet and use parenthetical disambiguation, and the least ambiguous qualifier is simply "chemistry". Mdewman6 (talk) 09:26, 19 November 2024 (UTC) — Relisting. Raladic (talk) 19:17, 26 November 2024 (UTC)

• Oppose for multiple reasons:

1. The page is in a state of flux with more work needed to remove unverified claims plus (slow) discussions to reorganize. Hence a move now would be premature.
2. I do not agree that "chemistry" is appropriate since there are aspects of toxicology, metallurgy etc. Instead "element" is the defining distiction. (Element could be put into brackets.)

More a comment: all the others you mention except light metal are only for elements. Both light metal and metal are not just elements and also not just chemistry. Ldm1954 (talk) 10:22, 19 November 2024 (UTC)

Addendum: I just noticed that @HertzDonuts moved the page from Heavy metal (elements) to Heavy metal element on Oct 27th without discussion. I suggest moving it back to what it was. Ldm1954 (talk) 11:32, 19 November 2024 (UTC)

• Support like Mercury (element), I don't think I've heard the term "Heavy metal element" so seems to be obscure per WP:NATURAL. Would Heavy metal (element) do instead? which matches mercury. Crouch, Swale (talk) 18:32, 19 November 2024 (UTC)

  I will support Heavy metal (element), with the additional comment that then Silicon (element) and Phosphorus (element) should be the disambiguation so everything is consistent. I searched most of the "element" pages, and did not see any more but there might be. Ldm1954 (talk) 19:28, 19 November 2024 (UTC)

• Propose Heavy metal (elements) — term refers to a class of elements, rather than a single element. Preimage (talk) 09:51, 20 November 2024 (UTC)

  Actually, Heavy metals might be a better name, see WP:Article titles#When a spelling variant indicates a distinct topic and WP:DIFFPLURAL. Looks like @HertzDonuts moved the page from Heavy metals to Heavy metal (elements) on Aug 6th. Edit summary was "singular title", which as detailed by those WP help links, doesn't necessarily apply here. Preimage (talk) 10:03, 20 November 2024 (UTC)

  I am OK with Heavy metal(s) (element(s)), all 4 options with and without the "s". I strongly oppose just Heavy metal(s). This page only discusss the elements, and most metals contain multiple elements. There are pages such as Metal, Refractory metal, Type metal, White metal in all of which there is no "element" in the name as they are more general and include alloys. Ldm1954 (talk) 10:19, 20 November 2024 (UTC)

• Agree with above proposals that Heavy metal (element) is a good title. The title of this page is an issue I've deliberated about for a while, that's why I made the moves. Using (element) as the distinguisher, then hypothetically there could be other future articles such as Heavy metal (toxicology) and Heavy metal (metallurgy). Singular title would also be consistent with other articles such as Alkali metal, Poor metal, etc. Still unsure if it should be (element) or (elements) but I lean towards (element) since it's better to lean towards singular forms in titles; I understand it is a group of elements, but saying "heavy metal element" in singular form is still valid. HertzDonuts (talk) 14:43, 23 November 2024 (UTC)

  Changed my mind to move to Heavy metals, because of WP:DIFFPLURAL and previous discussions linked below. HertzDonuts (talk) 22:36, 26 November 2024 (UTC)

To editors Mdewman6, Crouch, Swale, Preimage and HertzDonuts: it looks like there is enough concensus to support a move (in fact a revert) to Heavy metal (element). The only question remaining for me is whether we just WP:BEBOLD & change any other pages to be consistent or does that need an RfC? Ldm1954 (talk) 09:26, 25 November 2024 (UTC)

Well at least its consistent with mercury, I'm not sure about a RFC as I don't know about other pages but I think the main point of this RM is that there is consensus not to use the current natural disambiguation and that the qualifier "element" in the singular is the best choice. Crouch, Swale (talk) 09:31, 25 November 2024 (UTC)

We've been following the potentially controversial moves process, which provides a week for discussion (given sufficient participation; the proposed move's been signposted at WP:Requested moves/Current discussions and WP:WikiProject Elements#Article alerts). Provided they agree re: consensus, I expect an administrator (or other non-involved editor) to close the discussion in 1 day's time. Any resulting page move will leave a redirect from the current title Heavy metal element. So I imagine we'd only need to directly change a handful of other pages, e.g. the DAB page Heavy metal. In any case, move cleanup shouldn't require going through another comment process; we can discuss further here if needed. Preimage (talk) 11:11, 25 November 2024 (UTC)

Looking back to past moves here, it looks like the issue with Heavy metal (element) was that it made it sound like the article was about a specific element (like, mercury (element)) and we should not have the name carry that connotation. I somewhat agree there. I think Heavy metals would be acceptable per WP:PLURAL but would not be consistent with similar articles. So I think we should find the right disambiguator, either "element" or "chemistry" or something else. If there are other pages that appear to then require moving, there should be a subsequent RM to ensure consensus. I'm not sure what other pages would be affected by our choice here, though? Mdewman6 (talk) 01:07, 26 November 2024 (UTC)

If there isn't support for "chemistry" I would support a move back to "(elements)". Mdewman6 (talk) 01:11, 26 November 2024 (UTC)

Support original proposal: including the word "chemistry" is clearer and more helpful than the other suggestions.---Ehrenkater (talk) 09:30, 25 November 2024 (UTC)

One additional comment about "(chemistry)". Consider 14 carat gold. It is heavy, a metal, a chemical but not an element so it does not belong here with "(element)". Ldm1954 (talk) 13:41, 25 November 2024 (UTC)

That would be a mixture, not a chemical substance. HertzDonuts (talk) 22:33, 26 November 2024 (UTC)

Sorry, it is not a mixture, there is definite bonding between the Au and alloying elements. Ldm1954 (talk) 22:54, 26 November 2024 (UTC)

Minor addition; the bonding is not just entropy of mixing or VdW. A Bader charge analysis will show minor charge transfer. Ldm1954 (talk) 23:01, 26 November 2024 (UTC)

• Do not keep at this title. At best, this is a malformed disambiguation; this construct reads awkwardly and is never used in scientific texts. I would support a move to either Heavy metal (element) or Heavy metals but do not have a strong preference so long as the new title is MOS-compliant. ^Complex/_Rational 20:00, 26 November 2024 (UTC)
• rename back to heavy metals which was the result of a previous discussion. Graeme Bartlett (talk) 20:11, 26 November 2024 (UTC)
• Move to Heavy metals in agreement with the previous discussion. The plural is natural and covered by WP:DIFFPLURAL, i.e. the singular is ambiguous, but the plural is primary for the set of metallic elements considered "heavy". In terms of consistency, I think a parenthetical disambiguation and the plural are both inconsistent, but the plural has the edge on natural-ness and length. ― Synpath 21:09, 26 November 2024 (UTC)

  I didn't know about the previous discussion, and agree that this falls under WP:DIFFPLURAL; I now support Move to Heavy metals. HertzDonuts (talk) 22:37, 26 November 2024 (UTC)

Move to Heavy metals. WP:DIFFPLURAL seems to solve the problem nicely. </MarkiPoli> <talk /><cont /> 10:51, 27 November 2024 (UTC)

Cleaning: delete sections

To editors Johnjbarton and Smokefoot: and any others. I suggest deleting the Heavy metal element#Properties compared with light metals because:

1. Light metals are not just the elements, so the usage here is wrong.
2. Much of this is elsewhere in the article (better).
3. The physical properties part is misleading as it is always alloys in use, never single elements alone.
4. There are too many exceptions. Is Pb high melting? Is Au hard? Obviously not.

One step at a time -- Ldm1954 (talk) 10:52, 19 November 2024 (UTC)

As far as I can tell this section is synthesis: does any source provide a similar comparison of these categories? Johnjbarton (talk) 16:15, 19 November 2024 (UTC)

To editors Johnjbarton and Smokefoot: and any others. I deleted this section and removed a few more unverified source statements and general fluff. Please let me know if there is more dubious material. If I don't hear anything I will remove the unverified tag and move on. Ldm1954 (talk) 14:41, 9 December 2024 (UTC)

While I appreciate your work, my complaint about this article remains. Statements in the article can be verified in the sense that they say something about "heavy metals" but a large chunk of these cases mean "metals as toxic chemicals", the topic of Toxic heavy metal. I think the right fix is to ensure that such content is actually in the other article and remove it here. I hope to take that up some day. Johnjbarton (talk) 16:03, 9 December 2024 (UTC)

I have not problem with that. My main focus was removing material which the sources cited did not support, and removing material which had nothing to do with the elements (e.g. all the uses of alloys). Anything that depends upon the specific metal element and/or its ion is OK, for instance Pd/Pt catalysts or ruby lasers. Beyond that was fluff IMHO. There may still be some left (I noticed that you deleted one.)

Of course you would have to double-check that the sources in Toxic heavy metal actually say what is claimed. Ldm1954 (talk) 17:26, 9 December 2024 (UTC)

Yes, checking the sources is what takes all of the time. Johnjbarton (talk) 17:46, 9 December 2024 (UTC)

Delete #Strength- or durability-based

This section has nothing to do with heavy metal elements. Everything in this section is for various alloys, so this is a conflation that I think puffs up the article -- WP:SYNTH. In addition, grouping together the various alloys as this section does is awful metallurgy. W & Mo are brittle refractory alloys; lead is soft; copper is a good conductor and low corrosion...etc. N.B., adding Gd to reduce corrosion is spurious, it is way too expensive. Mo is the magic due to what it does with Cr, a still debated topic. Ldm1954 (talk) 14:04, 25 November 2024 (UTC)
