Overview
Overall this is close to a good article. However, while checking it in detail it became clear that various parts are identical to what is in the pages Manganese, Rhenium and Technetium. This is very troubling, and I think some edits are needed. There should also be definite links to these other pages as Main in various sections. Another area where significant work is needed is in the Applications section. These currently only describe, briefly catalysis and in some cases they have this wrong. I know there is far more for Rh than this article indicates. There is, critically, no mention of other uses. Both Mn and Rh are extensively used in alloys for example, by volume almost certainly the largest useage.

Other comments

 * In the lead, “markedly less coherent than the previous groups” needs rewording, as +7 is not in previous groups (do you mean empty sd-shells?) and “coherent” is an odd word here.
 * What do I use instead of "coherent"? Made the trend clearer.  141 Pr  {contribs} 07:41, 3 October 2023 (UTC)
 * It is not a "trend", as that references other groups and they don't have a +7 valence state. Also, please check the meaning "coherent" as that is certainly the wrong word.
 * A possibility is "The group 7 tend to have a major oxidation states with empty sd shells (+7 here). This empty sd maximum valent state is less definitive than some of the other transition metal series." Ldm1954 (talk) 13:41, 3 October 2023 (UTC)


 * I suggest a Figure for the oxides, maybe a structure. Figures help.

 * A better figure of chloro-containing compounds would be good. It is not clear what the reader is supposed to take from the figure.
 * There is no page Potassium hexachlorotechnetate.
 * Strictly not needed for GA.  141 Pr  {contribs} 07:43, 3 October 2023 (UTC)

This article needs some more work. Please try and accommodate the above then let me know. Then I can do the more formal GA review, checking the different criteria.
 * There are unsourced paragraphs, for instance the rhenium oxyhalides. Please ensure all paragraphs have adequate references.
 * In Organometallic compounds Why not reference the original Gilman and Bailee paper as well as the more recent review?
 * Please add a reference to Ogawa’s announcement
 * The Applications section is too narrow, as it only talks about catalysts.
 * Please borrow parts from Manganese for other areas. It is extensively used, and the current draft implies it is barely useful. Similarly Rhenium. It would be wise to do a bit more literature searching.
 * Also check Technetium. I would remove the corrosion result as it is very marginal at best. (The section in the Technetium page where this is suggested is also marginal.)
 * The Rh catalysts section is too sparse. Please look at, for instance, https://doi.org/10.1039/D1DT04205J and back/forth citations and expand slightly.
 * The Toxicity of Rh has been lifted verbatim from the Rhenium page. This is disturbing. Similarly the toxicity of Mn. Also the organotechnetium chemistry and Technetium are too similar.

✅, though do you mean Re instead of Rh?  141 Pr  {contribs} 07:38, 3 October 2023 (UTC)


 * Are you working on revisions? If not then perhaps it is best to close this review and let you reapply after some months when you have had a chance to revisr. Ldm1954 (talk) 10:45, 14 October 2023 (UTC)
 * A month has passed and there are no indications of any changes. Unless I see something in the next few days I will close the GAN as Ldm1954 (talk) 17:35, 16 November 2023 (UTC)

Addendum
There has been no attempt to improve the article and repair the major issues. It is therefore appropriate to close the GAN. Ldm1954 (talk) 13:53, 24 November 2023 (UTC)
