- citation [64] to page 102 of [1] doesn't seem to line up
Not done: not sure what to do.
- "but 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" Er... Emission bands of europium or terbium are commonly present in lights?
- I'm not sure what to do here.
- "Like most other metals in the lanthanide series, neodymium usually only uses three electrons as valence electrons, as after the remaining 4f electrons are strongly bound" I don't understand this sentence.
- Not done – please clarify
- "that spalls off and exposes the metal to further oxidation" To be clear, it spalls off without external force?
- Not done
- The chemical formulae in Chemical properties are unnecessary and clutter the text.
- The list of compounds should not include their full names (just wikilink their formulae), and relatively uncommon ones should be excluded.
- "Neodymium is a quite electropositive element" Needs to be more specific; how electropositive, or compared to what?
- Not done
- "7*10^18 years, approximately" Why approximately? If there's a huge error bar I'd say "on the order of 7*10^18 years" and then put the error in the isotope box.
- Not done
- The same reference is used in the article Praseodymium so I think it should be an RS. Bli231957 (talk) 12:46, 7 June 2022 (UTC)
- It's definitely not; it's a site that sells metallic samples, and has zero editorial oversight.
Not sure
- "Neodymium isotopes are used in various scientific applications." Well, sure... probably specify radioactive isotopes Ovinus (talk) 06:02, 4 June 2022 (UTC)
- Not done
- "Several neodymium isotopes have been used for the production of other promethium isotopes." Extremely vague; either specify which isotopes (of promethium, at least) or remove Ovinus (talk) 06:02, 4 June 2022 (UTC)
- Not done
- "didymos (διδύμος), twin.[8][26]..." Do we need six sources for an etymology? I'm assuming some of the sources are for previous sentences; I'd move them closer if possible Ovinus (talk) 06:02, 4 June 2022 (UTC)
- Not done
- "Because of its role ... for expanded production." Is this one source enough to include this sentence? (Do any other important sources make similar claims) Ovinus (talk) 06:02, 4 June 2022 (UTC)
- Not done
- I agree with the WP:TECHNICAL tag on Physical properties. Also, much of that section isn't even about physical properties—the lead sentence
Neodymium is the fourth member of the lanthanide series.
is not really a physical property. That stuff should go in Chemical properties. "Metallic neodymium has a bright, silvery metallic luster." should probably be first. See Caesium#Physical properties for a good example. What about other general properties, like conductivity, spectrum, density, melting point?
- Not done
- Solubility of neodymium salts in water is not discussed. Would be good to say that Nd+3 is generally soluble.
- Not done
- Strange language sprinkled throughout: "can access the midpoints of pressure and temperature regions"; "has been rapidly increasing owing to the growing population and industrial development" (growing human population? seems a bit obvious)
- Not done
- "due to the release of radioactive substances during the mining process" – Apparently a bit more description on the mining process is in order; why are there radioactive compounds being released?
- Not done
- Neodymium is a product of nuclear fission reactors (Nuclear fission product)
- Not done
- Listing of the various neodymium compounds needs to be done in prose form, grouping them by various qualities (color? solubility? etc). Otherwise it's a fairly useless collection
- Not done
Not sure
- Why is "R. J. Callow, The Industrial Chemistry of the Lanthanons, Yttrium, Thorium, and Uranium, Pergamon Press, 1967." in further reading? Ovinus (talk) 17:00, 7 June 2022 (UTC)
