Samarium

I've listed this article for peer review because I want to get a lanthanide to FA-class. This article seems promising, but would probably need a lot of improvement to get to FA-class, especially in the Chemical properties, Isotopes, and Biological role and precautions sections.

Thanks, ¹⁴¹Pr 08:57, 29 October 2022 (UTC)

STANDARD NOTE: I have added this PR to the Template:FAC peer review sidebar to get quicker and more responses. When this PR is closed, please remove it from the list. Also, consider adding the sidebar to your userpage to help others discover pre-FAC PRs, and please review other articles in that template. And, since you are still seeking your first successful FAC, I suggest seeking a FA mentor and start reviewing FACs now to build goodwill among the FAC regulars.

I have started improving the Isotopes section. I think that we just need more consistent referencing and more information in the sections you mentioned. InterstellarGamer12321 (talk) 18:50, 1 November 2022 (UTC)

Little notes

Not qualified to comment on science but just possible formatting improvements:

• Add alt tags - assume you’re a blind person using text to speech to read the article - what information would you need to "see" the image? - alt tags are also displayed when images don’t load for some reason.

  Done. ¹⁴¹Pr 17:20, 26 December 2022 (UTC)

• Use citation templates wherever possible — helps with visual consistency, metadata and networking etc.
  • 59 - cite web template, archive url in case goes dead someday

    Changed to cite web template, but couldn't find archive url. ¹⁴¹Pr 08:08, 31 December 2022 (UTC)

  • 70/71 - if in French language add | language=fr element to template

    Done. ¹⁴¹Pr 17:20, 26 December 2022 (UTC)

  • 75 - add OCLC or LCCN number to old books if you can find
  • 87 - cite journal - DOI 10.2113/gscanmin.40.6.1649 if you just put the DOI in the “automatic” tab of the cite tool it should do it for you

    Done. ¹⁴¹Pr 17:20, 26 December 2022 (UTC)

  • 88 - cite journal — DOI 10.1134/S1075701511070191

    Done. ¹⁴¹Pr 17:20, 26 December 2022 (UTC)

  • 102 - cite patent template

    Done. ¹⁴¹Pr 08:08, 31 December 2022 (UTC)

  • 103 - cite web template

    Done. ¹⁴¹Pr 08:08, 31 December 2022 (UTC)

  • 112 - archive url in case goes dead someday

ComplexRational comments

At first glance, this article has a solid content foundation, though certain sections could be expanded further, and the prose needs some work before it's ready for FAC. I'll do a more complete review in the coming days. Here are some initial considerations, mostly from two or three sections. I hope you don't mind if I nitpick, seeing as every detail potentially goes under the magnifying glass at FAC:

• In one study... – assuming this is referenced to Shi & Fort 1985, are there any more recent developments?

Can't find any more recent developments. ¹⁴¹Pr {^contribs/_{Best page}} 18:34, 13 February 2023 (UTC)

• the 3rd lowest among lanthanides – common stylistic convention is to write "third-lowest".

  Changed "3rd lowest" to "third-lowest". ¹⁴¹Pr 16:47, 26 December 2022 (UTC)

• They can also be doped – wikilink doped, and maybe explain what it means since it's not common knowledge.

  Wikilinked "doped", will add explanation later. ¹⁴¹Pr 17:33, 26 December 2022 (UTC)

Added explanation. ¹⁴¹Pr {^contribs/_{Best page}} 17:24, 12 March 2023 (UTC)

• the most recent class of high-temperature superconductor – "recent" is pretty vague; a more objective description would be better.

As I couldn't find when any more details, I removed it. ¹⁴¹Pr {^contribs/_{Best page}} 18:34, 13 February 2023 (UTC)

• Even when stored under mineral oil – this transition feels pretty abrupt.

  I don't think this transition feels abrupt, although I'm happy to change something if it's better for the article. ¹⁴¹Pr {^contribs/_{Best page}} 19:46, 27 March 2023 (UTC)

• that exhibit oxidation state +2 – rephrase to "that exhibit an oxidation state of +2" or "that exhibit the +2 oxidation state".

  Changed "exhibit oxidation state +2" to "exhibit the +2 oxidation state". ¹⁴¹Pr 16:47, 26 December 2022 (UTC)

• section Chalcogenides – check whether [40] references everything before it, otherwise additional inline citations are needed.

  I don't think it refers to all of the content before it, just that sentence. I will try to add some citations later. ¹⁴¹Pr 17:33, 26 December 2022 (UTC)

  Added citations. ¹⁴¹Pr {^contribs/_{Best page}} 19:46, 27 March 2023 (UTC)

• section Isotopes – there should be more than one sentence about samarium-146 as an extinct radionuclide (and any searches for it as a primordial nuclide).
• The long-lived isotopes ¹⁴⁶Sm, ¹⁴⁷Sm, and ¹⁴⁸Sm, primarily alpha decay to neodymium. – no comma is needed after ¹⁴⁸Sm, and these isotopes exclusively (not primarily) alpha decay to neodymium.

  Fixed this. I'm leaving it here as an example of some of the prose work needed before FAC. ^Complex/_Rational 19:45, 25 December 2022 (UTC)

• Check that the half-lives and count of isomers are up to date – {{NUBASE2020}} and possibly more recent articles in the literature are the go-to sources for this.

Seems to be up to date. ¹⁴¹Pr {^contribs/_{Best page}} 18:34, 13 February 2023 (UTC)

• Check if any isotopes lighter than ¹²⁸Sm have been reported or whether there are any unknown isotopes (i.e., discovery year and experimental half-life missing in NUBASE) in the given range – I've discovered a few gaps for some elements in a more careful review. I already updated on the heavy end with this year's article going up to ¹⁶⁸Sm.

  In fact, ¹²⁸Sm has not been reported (per NUBASE2020). I corrected the article to reflect this. ^Complex/_Rational 19:45, 25 December 2022 (UTC)

• A brief mention of the drug samarium (153Sm) lexidronam might also be appropriate since it deals with nuclear properties. Of course, it's described in greater detail later in the article, though I'm wondering whether the paragraph beginning with Samarium-153 is a beta emitter with half-life 46.3 hours would be better included in the isotopes section.
• This material is thought to have been used for nuclear control rods – thought to, by whom?
• which typically makes up only 1-2% of the original ore – change the hyphen to an en dash (MOS:DASH).

  Used template endash to change the hyphen into an en dash. ¹⁴¹Pr 16:47, 26 December 2022 (UTC)

• Domination of samarium in minerals is unique. Minerals with essential (dominant) samarium include monazite-(Sm) and florencite-(Sm). They are very rare. – usage of words such as "unique" and rare" in this context is not very descriptive or up to FAC standard. These should be described with comparisons and numbers (e.g., rarity in parts per million/billion).

  I have reworded this, and will add comparisons and numbers later. ¹⁴¹Pr 17:33, 26 December 2022 (UTC)

• for example in desulfonylation reactions; annulation; Danishefsky, Kuwajima, Mukaiyama and Holton Taxol total syntheses; strychnine total synthesis; Barbier reaction and other reductions with samarium(II) iodide – I wonder if any of these could be expanded upon; this listing suggests the existence of more research and applications worth describing.
• From the blood, ~45% goes to the liver and 45% is deposited on the surface – either approximate values or exact values should be consistently used.
• Overall, there are lots of short paragraphs, which would be better expanded when appropriate or consolidated.

  Which ones? ¹⁴¹Pr 17:33, 26 December 2022 (UTC)

  I see this most prominently in the isotopes and applications sections. As a reference, you can look at how some relatively recent element FAs are structured, such as fluorine, lead, and thorium. ^Complex/_Rational 00:32, 28 December 2022 (UTC)

More to come later, though I think a fair bit of improvement to prose (copyediting; criteria 1a) and completeness (criteria 1b and 1c) is required before this has a shot at FAC. ^Complex/_Rational 00:32, 25 December 2022 (UTC)

Thanks for taking up the review. (I had been taking a wikibreak earlier) I will try to complete as many of these as possible over the next few days. ¹⁴¹Pr 16:47, 26 December 2022 (UTC)

By the way, I have color-coded my comments above where purple means that I have completed that task, and green is an update, and orange is a question. ¹⁴¹Pr 17:33, 26 December 2022 (UTC)

@Praseodymium-141: No hurry with the review, and I like the color scheme so that it doesn't get too difficult to read through walls of text. However, I feel that we should focus on fleshing out content before copy editing prose, so would you prefer that I focus my subsequent comments on additions, layout, and references? ^Complex/_Rational 02:54, 31 December 2022 (UTC)

Sure, that is fine. I'll carry on with what is listed so far. ¹⁴¹Pr 08:08, 31 December 2022 (UTC)

Second pass – focus on content

@Praseodymium-141: Here are a few more spots I see for improvement, though I haven't done enough of my own research to accurately judge where expansion is needed. Apologies for the slow reviewing; I've been busy with other work on WP and IRL the last week. Will try to add more in the next few days.

• For physical properties, try to focus each paragraph on a specific aspect: bulk appearance/properties, different atomic structures, magnetism, superconductivity. This might also lead to some overlap and relocating information between this section and the following one on chemical properties.

I can't find enough information about magnetism and superconductivity, but I think there are enough information for the other two, so should I merge the two topics? ¹⁴¹Pr 19:34, 6 January 2023 (UTC)

Done. ¹⁴¹Pr {^contribs/_{Best page}} 19:46, 27 March 2023 (UTC)

• I recommend using {{convert}} for values so that, for instance, temperatures are given in Celsius and converted by the template to Fahrenheit.

Can you give me a place where the convert template doesn't get used? ¹⁴¹Pr 16:09, 6 January 2023 (UTC)

• Anywhere where only one unit is used, the earliest example being With boiling point 1794 °C. ^Complex/_Rational 04:18, 7 January 2023 (UTC)

Done. ¹⁴¹Pr {^contribs/_{Best page}} 18:34, 13 February 2023 (UTC)

• nonequilibrium annealing regime – too technical, expand upon this in layperson's terms
• Their corresponding effective magnetic moments, below 2μB – I think it would be beneficial to write the exact respective values, and also to spell out Bohr magneton on its first occurrence.

Spelt out bohr magneton, will find exact values later. ¹⁴¹Pr 16:40, 6 January 2023 (UTC)

• They are remarkable by converting from semiconducting to metallic state at room temperature upon application of pressure. – would prefer a more neutral term than "remarkable"

Reworded. ¹⁴¹Pr {^contribs/_{Best page}} 18:34, 13 February 2023 (UTC)

• one type of halide atom – should say "halide anion" or "halogen atom"

Changed to "halide anion". ¹⁴¹Pr 11:18, 6 January 2023 (UTC)

• ¹⁴⁹Sm is listed by various sources either as stable or radioactive, but only a lower bound for its half-life is given. – most up-to-date sources give it as stable, so I wouldn't give equal weight to reports of its radioactivity. I definitely support the inclusion of a numerical lower bound for its half-life (if nothing more specific, NUBASE gives 2×10¹⁵ years).

Included numerical lower bound for half-life. ¹⁴¹Pr {^contribs/_{Best page}} 17:24, 12 March 2023 (UTC)

• Talk a bit more about neutron absorbing properties of samarium isotopes in the isotopes section, while continuing to discuss specific applications later on.
• and is more common than elements such as tin – more context might help here (e.g., if this is relevant for Sm's cost), or alternatively, just cut this part out entirely.

I have added a clarification on what "common" is refering to. Is that what you were asking for? ¹⁴¹Pr 16:05, 6 January 2023 (UTC)

It reads better now, though I need to think on this one a bit more. ^Complex/_Rational 04:18, 7 January 2023 (UTC)

Clarified. ¹⁴¹Pr {^contribs/_{Best page}} 18:34, 13 February 2023 (UTC)

• in the remote Russian region of Urals – saying "the Ural Mountains in Russia" is equally correct and more neutral.

Changed to "the Ural Mountains in Russia". ¹⁴¹Pr 16:47, 6 January 2023 (UTC)

• ref 81 ([1]) is dead, so switch the archive URL.

Hello, I'm not sure how {{Webarchive}} template works, and I have read Help:Archiving a source, but I still don't understand it. Please can you give me a method on how to archive urls? ¹⁴¹Pr 18:54, 6 January 2023 (UTC)

I typically stick to {{cite web}} or similar templates; that's probably the easiest way to get this working. ^Complex/_Rational 04:18, 7 January 2023 (UTC)

Would something like this (commented out) work? ¹⁴¹Pr 08:19, 7 January 2023 (UTC)

Changed to the cite web template. ¹⁴¹Pr {^contribs/_{Best page}} 18:34, 13 February 2023 (UTC)

• In recent years it has been shown that nanocrystalline – when, and by whom?

^Complex/_Rational 02:38, 6 January 2023 (UTC)

Couldn't find who, but added year. ¹⁴¹Pr {^contribs/_{Best page}} 19:46, 27 March 2023 (UTC)

@ComplexRational: Sorry for the inactivity on this article for the past few weeks. I have fixed some of these issues today, and would probably be freer in the following few weeks to fix more. ¹⁴¹Pr {^contribs/_{Best page}} 18:34, 13 February 2023 (UTC)

@ComplexRational: I have fixed most of the issues in this peer review, is it OK for me to close it? ¹⁴¹Pr {^contribs/_{Best page}} 19:46, 27 March 2023 (UTC)

I'll take a quick look through the article again, but my time to do extensive editing has greatly diminished as of late – I apologize for not being more active with this review. If I don't post any more comments within the next week, go ahead and close it. ^Complex/_Rational 00:48, 28 March 2023 (UTC)

Been a week, closing. ¹⁴¹Pr {contribs} 19:49, 8 April 2023 (UTC)
