Review section

[edit]

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?
  • Has iridium been detected in any stars? How is it made? (is it binary neutron star mergers?)
  • 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]
  • Kittel, C. (2004). Introduction to Solid State Physics (7th ed.). Wiley-India. ISBN 978-81-265-1045-0. needs a page number rather than a whole book

  • Relación histórica del viage a la América Meridional → volume 1 does not appear to have 606 pages (only 404). Copies are online so it would be good to link to a page image for this ref. http://alfama.sim.ucm.es/dioscorides/consulta_libro.asp?ref=b19196386&idioma=0
  • 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]

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]

FARC section

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

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

  • Direct link to page for " The Playbook of Metals" → https://archive.org/details/playbookmetalsi00peppgoog/page/454/mode/2up
  • ALT text checking: mostly good except for File:Gama Supreme Flat Top ebonite eyedropper fountain pen 3.JPG and File:Elemental abundances.svg have nothing.
  • post-2016 consumption figures
  • Reference for "The only reported injuries related to iridium concern accidental exposure to radiation from 192 Ir"
  • radioisotope iridium-192 is one of the two most important sources for radiation.
