I will take on reviewing the article. It looks fine at first glance, but I'll look at it more thoroughly. Keres🌕Luna ^edits! 16:00, 21 June 2023 (UTC)[reply]

First comments

• Random ref check: reference 37 supports the statement that 'Europium triisopropylocene is a brown solid that can be reacted with hydrogen peroxide to give cyclopentadiene europium peroxide', could not find it in the article. Keres🌕Luna ^edits! 21:09, 21 June 2023 (UTC)[reply]

I cannot access this source. ¹⁴¹Pr {contribs} 11:49, 22 June 2023 (UTC)[reply]

If the source cannot be verified, it should be removed with the following statement, or another reference should be found. Keres🌕Luna ^edits! 16:53, 22 June 2023 (UTC)[reply]

Couldn't find any refs for that, so I removed it. ¹⁴¹Pr {contribs} 20:54, 22 June 2023 (UTC)[reply]

• 'Eu(fod)3 serves as a Lewis acid' what does fod stand for?

Made more clear what the fod stood for. ¹⁴¹Pr {contribs} 11:47, 22 June 2023 (UTC)[reply]

• The aspect that Europium compounds fluoresce under UV is a pretty important topic, and I don't see anywhere explaining why or at least how in the article, only mentioned briefly in the captions. This probably fails Criterion 3a, as it fails to introduce a major aspect.

I have addressed it in the lead, although I don't think it needs any further info. ¹⁴¹Pr {contribs} 12:35, 25 June 2023 (UTC)[reply]

• Earwig found minor plagiarism on 'Europium(III) phosphide is a semiconductor used in high power, high-frequency applications and in laser diodes.', which the statement is copied off from ref 43. Also, American elements is not a reliable source according to WP:VENDOR.

Removed sentence along with the source. ¹⁴¹Pr {contribs} 19:45, 22 June 2023 (UTC)[reply]

• The captions of the images are unreferenced, especially the statement that 'Europium compounds fluoresce under UV light at 395 nm and 365 nm.'

Added a reference to the caption of the top video, couldn't find refs for the reaction one. ¹⁴¹Pr {contribs} 12:37, 25 June 2023 (UTC)[reply]

• A sortable table like Terbium compounds would be nice.

Added a table, although I don't see why it should be sortable. ¹⁴¹Pr {contribs} 12:26, 25 June 2023 (UTC)[reply]

• The article is missing information on europium selenides, and should be added in the chalcogenides section.

Added info about other europium chalcogenides apart from sulfides. ¹⁴¹Pr {contribs} 12:57, 25 June 2023 (UTC)[reply]

• More info on various compounds is needed. For example, more info is needed on europium(III) hydroxide, and the halide section should be expanded. Keres🌕Luna ^edits! 01:46, 24 June 2023 (UTC)[reply]

Done. ¹⁴¹Pr {contribs} 16:01, 25 June 2023 (UTC)[reply]

These comments would take a long time, I'll get started later. ¹⁴¹Pr {contribs} 08:30, 24 June 2023 (UTC)[reply]

Ok, I will put it on hold until the comments are addressed. Keres🌕Luna ^edits! 14:15, 24 June 2023 (UTC)[reply]

@Keresluna: I have addressed all comments, it didn't actually take that long. ¹⁴¹Pr {contribs} 16:01, 25 June 2023 (UTC)[reply]

Is there any information about europium pnictogenides? If not, add information about them too. Keres🌕Luna ^edits! 16:37, 25 June 2023 (UTC)[reply]

I could only find information about the nitride and phosphide, but not the arsenide, antimonide and bismuthide. Is that OK? ¹⁴¹Pr {contribs} 17:58, 25 June 2023 (UTC)[reply]

Yes, that is okay. Keres🌕Luna ^edits! 19:02, 25 June 2023 (UTC)[reply]

Done. ¹⁴¹Pr {contribs} 16:42, 26 June 2023 (UTC)[reply]

I have added information about europium arsenides if that's okay. Keres🌕Luna ^edits! 21:25, 26 June 2023 (UTC)[reply]

Yes, that's fine ¹⁴¹Pr {contribs} 06:23, 27 June 2023 (UTC)[reply]
