Hello, I'm Reconrabbit. I did an initial pass through of the article but will look more in depth as I go through the criteria. As an opening note, Praseodymium-141, the nominator, has contributed 45.9% of the article according to XTools. Reconrabbit 17:59, 22 March 2024 (UTC)
I'm not going to go any further on this review until the copied text is addressed.Reconrabbit 20:12, 22 March 2024 (UTC)- Thanks for taking up this review. I will look at your initial comments over the next few days. 141Pr {contribs} 21:16, 22 March 2024 (UTC)

- I've just gotten back home late last night. I'll do a source check and then complete the review. Reconrabbit 13:46, 11 April 2024 (UTC)
- There have been a ton of issues coming up with the source checks. I'm not sure I can pass this. Will ask for a second opinion. Reconrabbit 16:06, 16 April 2024 (UTC)
- @Reconrabbit: friendly reminder. 141Pr -\contribs/- 09:22, 12 May 2024 (UTC)
- After trying to solicit a second opinion for almost a month without success I don't feel like the article can pass right now. Too many of the sources are low quality or couldn't be verified. This week I can go looking to see if I can address the last few things on my own, but there are still sources I haven't checked that could have similar issues. Reconrabbit 02:32, 13 May 2024 (UTC)
- The current article just has far too many source issues. I will have to fail it for now. Reconrabbit 19:22, 18 May 2024 (UTC)

GA review – see WP:WIAGA for criteria
- Is it well written?
- A. The prose is clear and concise, and the spelling and grammar are correct:
- B. It complies with the manual of style guidelines for lead sections, layout, words to watch, fiction, and list incorporation:
Lead section, second paragraph:This color changes with the type of lighting because of the interaction of the sharp light absorption bands of neodymium with ambient light enriched with the sharp visible emission bands of mercury, trivalent europium or terbium.
This sentence is kind of run-on and needs to be rewritten, since it's a little too complex for the lead.- Shall I remove the entire explanation or just the enriched part? 141Pr {contribs} 08:19, 7 April 2024 (UTC)
- On revision: this isn't that much of an issue and is clarified in the text. Reconrabbit 15:25, 11 April 2024 (UTC)
- Shall I remove the entire explanation or just the enriched part? 141Pr {contribs} 08:19, 7 April 2024 (UTC)
Neodymium-doped glasses
could it be clarified that this means "glass that has been doped with neodymium"? Only because there is quite literally a photo of a pair of glasses later on.- Clarified. 141Pr {contribs} 07:33, 7 April 2024 (UTC)
History, second paragraph:The evolving technology, and improved purity of commercially available neodymium oxide, was reflected in the appearance of neodymium glasses in collections today.
This sentence feels out of place. Maybe reword to exclude "evolving"?- I agree that this sentence feels out of place. However, I don't know how to reword it either. Shall I remove it? 141Pr {contribs} 08:18, 7 April 2024 (UTC)
- Find a better way to say "neodymium glass technology improved" or don't bother saying it at all, I think. Reconrabbit 15:14, 7 April 2024 (UTC)
- Reworded I guess. I'm not sure if it is better though. 141Pr {contribs} 16:28, 7 April 2024 (UTC)
- The wording is more straightforward and sticks out less in the paragraph, which I see as an improvement. Reconrabbit 15:25, 11 April 2024 (UTC)
- Reworded I guess. I'm not sure if it is better though. 141Pr {contribs} 16:28, 7 April 2024 (UTC)

History, third paragraph:Because of its role in permanent magnets used for direct-drive wind turbines, it has been argued that neodymium will be one of the main objects of geopolitical competition in a world running on renewable energy. This perspective has been criticised for failing to recognise that most wind turbines do not use permanent magnets, and for underestimating the power of economic incentives for expanded production.
This is a weird inclusion and may be better added under applications. There's also a tone problem here. Sources are apparently reliable, but there has to be a more neutral way of saying this.- I'm not sure what to do with this paragraph, but it certainly feels out of place. Shall I remove it? 141Pr {contribs} 08:18, 7 April 2024 (UTC)
- I would say remove it. Interested parties can write their own article on the geopolitical implications of the rare earth metals. Reconrabbit 15:14, 7 April 2024 (UTC)

Production, first paragraph: Clarify "radioactive substances" that are being released. Are these just Thorium as shown in the diagram?- Done. 141Pr {contribs} 07:12, 6 April 2024 (UTC)
Production, third paragraph:NdFeB magnets are used in hybrid electric vehicles (HEVs)...
Why are all of these applications provided with abbreviations even though they are never mentioned again later in the article? The most egregious of these is "hereinafter referred to as xEVs".- rmved abbreviations. 141Pr {contribs} 07:12, 6 April 2024 (UTC)
Applications: Starting off with a list is awkward. Consider rewriting this as prose or providing a lead-in sentence to clarify why these particular uses are being listed.- I'm not sure what to do with this lol. I put a very short lead sentence that doesn't really add anything new. 141Pr {contribs} 07:49, 7 April 2024 (UTC)
- That's fine. Reconrabbit 15:14, 7 April 2024 (UTC)

- A. The prose is clear and concise, and the spelling and grammar are correct:
- Is it verifiable with no original research?
- A. It contains a list of all references (sources of information), presented in accordance with the layout style guideline:
- "Lodders 2003" is broken. Chemistry of the Elements (2nd ed.) in the bibliography is not cited directly anywhere in the article. Nature's Building Blocks: An A-Z Guide to the Elements is cited, but not with sfn, so either remove the entry in the bibliography or the named reference in References.
- Removed entry in the bibliography. (I think I added it when I didn't know what a bibliography was for, when I just started editing Wikipedia) 141Pr {contribs} 21:23, 22 March 2024 (UTC)
- The other items in the bibliography either have to be removed or renamed as "further reading", because there's no indication of relevance to Nd. Reconrabbit 15:36, 23 March 2024 (UTC)
- Done. 141Pr {contribs} 08:54, 24 March 2024 (UTC)

- Reading more in-depth here, there are a few citations that should have been Sfn formatted but are just plain text. I highly recommend going over these and changing the way they are displayed (either add back the bibliography or just turn these into standard citations with page numbers): Emsley, pp.120-5 and all instances of Greenwood and Earnshaw
- Fixed all the sfn stuff. 141Pr {contribs} 08:03, 7 April 2024 (UTC)
- Great work. Reconrabbit 15:14, 7 April 2024 (UTC)

- B. Reliable sources are cited inline. All content that could reasonably be challenged, except for plot summaries and that which summarizes cited content elsewhere in the article, must be cited no later than the end of the paragraph (or line if the content is not in prose):
- There are still two present "citation needed" tags. I've added additional maintenance templates. Reconrabbit 16:14, 25 March 2024 (UTC)
- I've gone through as much as I can - I can't find any reference for the remaining [citation needed] tag, and don't know what to do about the [clarification needed] tag in "Biological role and precautions". 141Pr {contribs} 08:37, 7 April 2024 (UTC)
- It seems hard to believe that there are no sources on the formation of neodymium hydroxide, but the page on that doesn't give the best sources either. If this is not a particularly important compound of Nd, I would remove the statement; otherwise, use the citation on the page and indicate that it forms in ammonia water as stated. As for the clarification - my question here is what is meant by "effective". Maybe it would be better to state that neodymium is among the lanthanides found to have a biological role in these bacteria. Reconrabbit 15:14, 7 April 2024 (UTC)
- Well, for the [citation needed] tag I just noticed that I could've used the citation used in the halogen bit. For the clarification, I have removed the "effective" part and just stated that neodymium has a biological role in the bacteria. 141Pr {contribs} 16:41, 7 April 2024 (UTC)

- Source spot check (~20%) based on this revision:
- [8] · [11] · [25] · [21] Reference is identical to [22].
- [20]
Source only confirms the 0 state for Nd; +2 and +4 are mentioned only in the context of samarium, ytterbium, cerium and europium.
- On checking this is the same source as [4]; it only refers to the 0 oxidation state. 141Pr {contribs} 11:11, 12 April 2024 (UTC)
- [10]
Source is a press release and does not discuss Nd permanent magnets. A better source is guaranteed to exist.
- Added a better source. 141Pr {contribs} 11:06, 12 April 2024 (UTC)

The page number isn't right here - should be 100?
- Changed the page to 100. 141Pr {contribs} 16:59, 11 April 2024 (UTC)

This decribes fractional crystallization but does not describe the preceding information about glass.
- I think it is just referring to
Early neodymium glasses made in the 1930s have a more reddish or orange tinge than modern versions, which are more cleanly purple, because of the difficulties in removing traces of praseodymium using early technology, namely fractional crystallization
, not the rest. 141Pr {contribs} 16:59, 11 April 2024 (UTC)- Then shouldn't there be a citation for "early neodymium glasses have a more reddish or orange tinge"? I can't find any reference to this in the text unless it's in a different chapter. Reconrabbit 17:32, 11 April 2024 (UTC)
- What? I don't understand your comment. 141Pr {contribs} 11:06, 12 April 2024 (UTC)
- I cannot find where this source supports "Early neodymium glasses made in the 1930s have a more reddish or orange tinge than modern versions".
- Shall I find a source that supports this? 141Pr {contribs} 16:53, 12 April 2024 (UTC)
- Please do. If there isn't a source, only include the information supported by the current source. Reconrabbit 17:09, 12 April 2024 (UTC)
- Well, I couldn't find any sources about it. What shall I remove? 141Pr {contribs} 17:57, 12 April 2024 (UTC)
- Since this writing doesn't point to the impurities developing any particular colors in the glass, the best thing to do with what you have is to write on how early methods of separating the lanthanides depended on fractional crystallization, which did not allow for the isolation of high-purity neodymium until the aforementioned ion exchange methods were developed after World War II. Reconrabbit 18:08, 12 April 2024 (UTC)
- Do you think

unless it's referring to the brief section on the rare earths?
- I don't understand your comment - can you clarify please? 141Pr {contribs} 11:06, 12 April 2024 (UTC)

Refers to only "chief ores", not "space" or "crust abundance". Maybe best to use this only for the "in the crust" section.

- [54] Text does not directly mention the Paris Agreement, but all other attributed content is acceptable.
- [57] Source states the opposite of what is claimed - "Samarium-cobalt magnets corroded quickly within 24 hours", and the article says "neodymium-based magnets lose their magnetism at lower temperatures[55] and tend to corrode,[56] while samarium–cobalt magnets do not."
- [62] While it does support the text, there has to be a better source than a website that has "Add to Basket" as the first thing you see.
