Notified: FAC nominator indeffed years ago and not notified, Itub, Stone, Cryptic C62, Materialscientist, Wbuchma, Mav, WP Elements, WP Geology, WP Rocks and minerals, noticed August 5

Back on August 5, I noted issues on talk with datedness, lead issues, failed verification, and poor sourcing. While this resulted in the article being pulled from the TFA schedule, the issues have not been addressed. Hog Farm _Talk 15:10, 9 September 2022 (UTC)[reply]

• Comments from Graeme Bartlett: Some things are missing
• We need an update as to prices and production or use figures to the present date. updated table still missing.--Stone (talk) 15:28, 9 October 2022 (UTC)[reply]
• Also has there been any new isotopes discovered in the last 20 years?

• The list in isotopes of iridiu is based on NUBASE2003 the update to NUBASE 2020 doi:10.1088/1674-1137 gives several new from ¹⁶³Iridium upto ²⁰⁵Iridium doi:10.1016/j.nds.2020.05.001--Stone (talk) 21:46, 1 November 2022 (UTC)[reply]

The doi:10.1088/1674-1137 does not seem to work. Horsesizedduck (talk) 16:59, 17 January 2023 (UTC)[reply]

• The metal working section just seems historical. How do people work it nowadays? What do jewelers do? How are crucibles made?

• This is the historic section, so the new stuff is in the applications section.--Stone (talk) 08:08, 9 October 2022 (UTC)[reply]

• How is ¹⁹²Ir produced? [2] [3] [4] --Stone (talk) 15:26, 4 October 2022 (UTC)[reply]
• How much iridium is in igneous rocks, including the enriched ones? How much concentration in the mantle? And re there any guess as to its concentration in the core?

• nice nubers for ocean water doi:10.1126/science.273.5281.1524 or the marine sediments doi:10.1007/978-1-4419-8694-8_10

• Has iridium been detected in any stars? How is it made? (is it binary neutron star mergers?)

• doi:10.3847/2041-8213/ac26c6 The r-process and as you said the binary neutron star mergers.--Stone (talk) 12:51, 5 October 2022 (UTC)[reply]

• Included --Stone (talk) 09:38, 1 November 2022 (UTC)[reply]

• There is no popular culture section, but please check if there are secondary references for use of "iridium" in culture of any kind. (books games plays music)
• Lesser issues: http://www.platinum.matthey.com/uploaded_files/Pt2008/08_complete_publication.pdf is a dead link (it's the only one I checked so there may be more?).

• updated link to new website style--Stone (talk) 09:38, 1 November 2022 (UTC)[reply]

• much of the property information in the infobox is unreferenced. Or even if it is by clicking through, is hard to locate references.
• A photo of an iridium compound would be good.
• In the text it mentions "volatile new oxide" but it appears that this is the osmium oxide. So might be best to explain that.
• Occurrence in the crust graph does not match text. It looks as if iridium is the rarest, not the same as tellurium. (though graph is by number of atoms).

• This is because of the mentioned atoms versus weight issue.

• Density - there is a claim around that iridium density is higher than osmium under pressure. Probably this should be mentioned.
• "Densities of Osmium and Iridium". Technology.matthey.com. is incompletely referenced - appears to be a journal article - easy to fix. changed to journal reference --Stone (talk) 08:17, 27 September 2022 (UTC)[reply]

• A system of chemistry of inorganic bodies page 693 does not mention "ptene" - perhaps page is wrong. Or perhaps volume is wrong, the link is for volume 2 but reference does not state the volume. https://archive.org/details/asystemchemistr07thomgoog/page/692/mode/2up Yes this mentioned in the first volume, changed the link and added volume = 1 .--Stone (talk) 11:02, 27 September 2022 (UTC)[reply]

• Isotopes ²⁰⁴Ir is claimed in https://journals.aps.org/prc/abstract/10.1103/PhysRevC.84.011601 ²⁰⁵Ir is claimed in https://doi.org/10.1016/j.physletb.2012.09.021 Graeme Bartlett (talk) 03:42, 11 September 2022 (UTC)[reply]

Not many options of photos for this element's compounds. If a user could upload a new photo, that would be great, but in the meantime I chose File:Sodium hexachloroiridate(III) hydrate.jpg with alt text Inorganic pale brown powder and a crossref to a foreign-language article on the compound shown. Other options were File:Ir2Cl2(cod)2.jpg, File:Vaska's-complex-sample.jpg, and two blurry crystal samples of lithium iridate. –LaundryPizza03 (dc̄) 03:34, 15 September 2022 (UTC)[reply]

• The history section quotes a book by Antonio de Ulloa in 1748 as the first mentioning of platinum alloys. This is wrong and not stated in this way in the platinum article. This section should be copied from the more recent FA articles. --Stone (talk) 12:26, 26 September 2022 (UTC)[reply]

Issues raised in the review section include currency and sourcing. Nikkimaria (talk) 02:19, 24 September 2022 (UTC)[reply]

• @Stone: - I see you've been improving the reference formatting. Do you think you'll also be able to work on the failed verification/datedness/etc? Hog Farm _Talk 15:40, 5 October 2022 (UTC)[reply]
• Delist, issues remain and the image layout and sandwiching problems are another indication of subpar article. SandyGeorgia (Talk) 13:37, 7 October 2022 (UTC)[reply]
• Delist - improvements so far have only scratched the surface issues. Hog Farm _Talk 20:03, 7 October 2022 (UTC)[reply]
  • Hold, given the ongoing work. Stone please keep us periodically updated on progress. Hog Farm _Talk 15:18, 15 October 2022 (UTC)[reply]
• Delist--Guerillero ^{Parlez Moi} 20:58, 10 October 2022 (UTC)[reply]
• Delist Citation concerns remain, and I am concerned about the structure of the "Industrial and medical" section. Z1720 (talk) 16:49, 14 October 2022 (UTC) Striking for now, as I see @Stone: is addressing concerns per below. Hopefully they will give a comment about their progress and expected timeline. Z1720 (talk) 22:24, 14 October 2022 (UTC)[reply]
• Wait Stone is gradually addressing all the concerns that I raised. Graeme Bartlett (talk) 22:19, 14 October 2022 (UTC)[reply]
• Wait as per Grame Bartlett. ¹⁴¹Pr 08:41, 16 October 2022 (UTC)[reply]

• Still a few things to do but mostly small things, but a few I can not do. --Stone (talk) 14:41, 14 November 2022 (UTC)[reply]

• Stone's last edit on Wikipedia was Nov. 14, and Smokefoot made some large edits last week. Is this article ready for more reviews, or are more edits needed? Z1720 (talk) 15:16, 17 December 2022 (UTC)[reply]

  Reaffirming my delist from October. There are incomplete citations, an image layout mess, and update needs throughout. As but one sample, this text cited to a 1999 source: "The tip material in modern fountain pens is still conventionally called "iridium", although there is seldom any iridium in it; other metals such as ruthenium, osmium, and tungsten have taken its place.[97]". SandyGeorgia (Talk) 12:17, 10 January 2023 (UTC)[reply]

• Back to delist - has been stalled out for some time, and there's still material that needs checked for updates/newer sources, such as "At least 32 metastable isomers have been characterized," to a source from 2003; copyedit/prose work needs such as "Iridium in its complexes is always low-spin)." [unclear if the closing parenthesis is on purpose or an accident]; and citation problems such as citing an entire book. This still needs work, which hasn't been happening at an appreciable rate since early December. Hog Farm _Talk 21:35, 27 January 2023 (UTC)[reply]

update section

• Isotopes of iridium should be update to NUBASE 2020 doi:10.1088/1674-1137.

• Concentration in igneous rocks, including the enriched and in the mantle.?
