 * Hey Amitchell, I've recently been feeling unwell. You are welcome to place comments on the review, but there might be a long delay before I respond to them.  141 Pr  {contribs} 18:51, 18 July 2023 (UTC)

Happy to review the article. AM

Initial comments on the references
(see MOS:REFERENCES for information regarding these comments)

The following is based on this version of the article. The citation method chosen for this article needs to be more consistently applied:
 * There is a Bibliography section, but this only lists two books. Refs 6, 9. 10, 11, 21, 25, 26, 28, 29, 30, and 35 are also books, and so for consistency should also be listed in the bibliography. Ref 56 is unnecessarily listed in both sections.
 * I have added those books to the bibliography. Is that what you mean? Also, can you explain to me what means?  141  Pr  {contribs} 08:00, 7 August 2023 (UTC)
 * The Ref 56 (Emsley) issue is now sorted. However you still have a mixture of different citation styles, e.g., Ref 16 (Emsley, John (2011). Nature's Building Blocks. p. 226.) is a short quote, and Ref 8 (Cullity, B. D.; Graham, C. D. (2011). Introduction to Magnetic Materials. John Wiley & Sons. ISBN 978-1-118-21149-6) is a full citation, but without a page number. Amitchell125 (talk) 13:27, 7 August 2023 (UTC)
 * ✅  141 Pr  {contribs} 15:01, 9 August 2023 (UTC)


 * Is the date for Ref 17 correct? A different date is given in the Bib section.
 * They seem to be different books, although I'm not sure.  141 Pr  {contribs} 16:50, 28 July 2023 (UTC)
 * They are different editions of the same book—information in 2011 (p.225) lines up with the text in 2001 (p.181). Both books can be viewed in full online here, you should I think only select one of them. Amitchell125 (talk) 19:01, 4 August 2023 (UTC)

 * ❌ Refs 9, 15, 16, 22, 25 , 28, 29, 30, 35, 41 require page numbers for me to verify the text.
 * ❌ Ref 26 has a range of pages, not a single page.
 * ✅  141 Pr  {contribs} 16:23, 9 August 2023 (UTC)


 * Ref 40 appears to have an incorrect title. The ref should be written as

 * Refs 39 and 62 cannot be used to verify the text, as they are general links.
 * ✅  141 Pr  {contribs} 07:44, 7 August 2023 (UTC)


 * Ref 28 links to a WorldCat page, this link is of little use. The link to Ref 43 is of little use, I would use this.
 * ✅  141 Pr  {contribs} 16:50, 28 July 2023 (UTC)


 * Ref 12 shouldn't be in capitals.
 * ✅  141 Pr  {contribs} 16:09, 24 July 2023 (UTC)


 * (not GA) Consider putting 'url-access=subscription' into Refs 7, 8, 13, 19, 24, 27, 31, 46, 47, 50, 51, 53, 57, 58, and 59.
 * ✅  141 Pr  {contribs} 07:37, 7 August 2023 (UTC)


 * (not GA) There are urls available for Refs 9, 16, 28, and 30, which I would consider using.
 * 9 already has a url, the others I can't find.  141 Pr  {contribs} 15:16, 9 August 2023 (UTC)


 * (not GA) Ref 35 is too old for an ISBN number, but an OCLC number is available, which I would consider using.
 * Couldn't find any OCLC number.  141 Pr  {contribs} 15:16, 9 August 2023 (UTC)


 * Ref 28 is in German; consider adding 'language=de' (normal practice)
 * ✅  141 Pr  {contribs} 16:09, 24 July 2023 (UTC)


 * The following references appear to be dead links: 33, 34, 36, 37, and 61.
 * Ref 33 and 34 seem to be working for me, it seems like a French archive though.  141 Pr  {contribs} 07:47, 7 August 2023 (UTC)
 * And for me as well, not sure what happened... AM


 * Ref 29 needs a volume number.
 * Couldn't find ref 29 online (at least published in 1963).  141 Pr  {contribs} 11:36, 9 August 2023 (UTC)
 * I found 2 volumes, and holmium isn't in either. See this. Amitchell125 (talk) 12:06, 9 August 2023 (UTC)
 * ✅  141 Pr  {contribs} 14:51, 9 August 2023 (UTC)

I'll do the others later.  141 Pr  {contribs} 16:09, 24 July 2023 (UTC)
 * The Refs 9, 15, 16 require page numbers for me to verify the text. As I am working through the article section by section, I cannot easily continue until these page numbers are provided. Can you address this issue please? Amitchell125 (talk) 13:56, 28 July 2023 (UTC)


 * Link malleable (Ductility, here and in the following section); oxide; Earth's crust; spectroscopically (Spectroscopy); ions; fluorescent (Fluorescence);emission light lines (Emission spectrum); laser; neutron; nuclear reactor.

 * independently by - ‘independently by the Swiss chemists’. Were they acting together? The text could be read to mean they were not.
 * How do I phrase it so that it is more obvious?  141 Pr  {contribs} 15:18, 2 August 2023 (UTC)
 * Something like 'Holmium was discovered through isolation by Swedish chemist Per Theodor Cleve. It was also independently by Jacques-Louis Soret and Marc Delafontaine, who together observed it spectroscopically in 1878'. AM

 * Something Holmium is quite electropositive and is generally trivalent with something like 'On a electronegativity scale going from 0.7 (for the highly electropositive francium) to 2.98 (for the most electronegative element, fluorine), holmium is electropositive with a value of 1.23. '

 * How do I phrase it without starting with 35? Can you give me an example?  141 Pr  {contribs} 17:14, 30 July 2023 (UTC)
 * Something like: 'Of the 35 synthetic radioactive isotopes that are known, the most stable one is holmium-163'. Amitchell125 (talk) 16:22, 31 July 2023 (UTC)

 * Apologies, I meant from and most have... to the end. Amitchell125 (talk) 16:24, 31 July 2023 (UTC)
 * Couldn't find any reference about 166m1Ho.  141 Pr  {contribs} 15:38, 4 August 2023 (UTC)
 * Suggest: 166m1Ho has a half-life of around 1200 years. (cite using this, which also lists interesting medical applications for 166Ho in the Abstract at the top of the article) The high excitation energy, resulting in a particularly rich spectrum of decay gamma rays produced when the metastable state de-excites, makes this isotope useful as a means for calibrating gamma ray spectrometers. (cite using this; also Emsley (2011), p. 226)

 * Hi, the refs need sorting still, an issue that will cause the article to be failed. Do you need a few more days? Amitchell125 (talk) 17:52, 6 August 2023 (UTC)
