Chemicals Discussion

The discussion here concerns all parts of the Chemicals WikiProject, including the infoboxes, lists, standards, includes/excludes, tools, contributors, etc etc etc. Feel free to add your comments to any section here, or start a new topic. Topics not specifically related to the Chemicals WikiProject would be better served at other wikipages.

Actual wikiproject info: statistics and alerts

WPChem worklist pages by quality Quality Total FA 2 GA 16 B 172 C 76 Start 111 Stub 14 List 1 NA 3 Assessed 395 Total 395 WikiWork factors (?) ω = 1,491 Ω = 3.81

The worklist shows the actual work to be done to achieve the goals of the Chemicals wikiproject. The choice of important compounds articles to work on has been finalized in an earlier stage of the wikiproject (around mid 2005), and no further articles are added, although we remain open for strong suggestions on this talkpage. The work these days focuses on improving the articles, from Chem Stub all the way to Chem A-Class articles. The table below shows that progress.

The percentage ≥ Chem Start was indicative of the initial effort. Now that we are progressing to more advanced progress, the weighted progress indicator is used, calculated as (Unclass*0 + Stub*1 + Start*2 + B-Class*3 + A-Class*4) / (Articles*4).

Fluorine peer review

Please review and fix "Fluorine". In particular, I know there are some top notch practicing chemists here. What I want is a check of the science, especially the structural compound review at the end for mistakes in fact or emphasis. Thanks.-TCO

FA articles not in the CHEM AQ overview?

I do not understand why not all qualities are in the quality overview. E.g. Category:FA-Class chemicals articles. -DePiep (talk) 15:10, 26 December 2013 (UTC)

It is something to do with Template:WikiProject Chemicals but I can't figure it out. Graeme Bartlett (talk) 10:31, 25 January 2014 (UTC)

2-Carbomethoxytropinone

This article is currently at AFD: Misplaced Pages:Articles for deletion/2-Carbomethoxytropinone. If anyone would like to help out, the article and the AFD would benefit from the attention of additional chemists. -- Ed (Edgar181) 13:05, 2 January 2014 (UTC)

Nomenclature-based renaming

See Talk:NBOH-2C-CN where several articles are requested to be renamed using a different nomenclature -- 70.50.148.122 (talk) 03:34, 18 January 2014 (UTC)

Is an amalgam an alloy?

Amalgam (chemistry) defines itself as a "substance formed by the reaction of mercury with another metal" (links omitted, italics mine). It never says it is an alloy, but that term is used in one of the later sections and the alloy article gives amalgams as an example. There are scattered questions over years on the talkpage asking several related questions, getting at the concern that the article never really discusses the nature of this "reaction" or its resulting "substance". How is it other than just an alloy where one of the components is specifically mercury? DMacks (talk) 16:01, 24 January 2014 (UTC)

Greenwood and Earnshaw refers to amalgams as alloys. IUPAC does not define the term. Not that I know of any other alloy with NH₄. BTW, the article suggests Hg-H bonds for the ammonium derivatives, which seems unlikely. There must be a book on amalgams, but searching turns up a lot of things on dentistry. --Smokefoot (talk) 23:44, 24 January 2014 (UTC)

Ammonium phosphate

This is rated as high importance but is a stub because the salt (NH₄)₃PO₄ is unstable. I suspect the importance stems from the use of ammonium phosphates in agriculure, but the fertilizer ammonium phosphates are diammonium phosphate and monoammonium phosphate which are both rated as low importance, the former is a "stub" and the latter a "start". There is also an ammonium phosphate (compounds) index page. Could we possibly change the importance rating on these compounds?Axiosaurus (talk) 14:05, 27 January 2014 (UTC)

I have changed it to low. I think you could have just gone in and changed it yourself rather than seeking a consensus. Perhaps we need more explicit rules on what is high, or medium importance, and a consensus for each article with "top". Graeme Bartlett (talk) 20:55, 27 January 2014 (UTC)

Also I changed MAP and DAP to mid. I think that any chemicals manufactured and sold in large quantities should be at least mid (if not high) importance. What do others think? Graeme Bartlett (talk) 21:03, 27 January 2014 (UTC)

The chemicals work list has stood the test of time quite well. I think any changes require a concensus, or at least flagging up to the wider community. Factors like commercial significance are part of the story but whilst some inorganics are significant in that regard, thousands or even millions of tons pa. , some are almost unknown to the general public. Axiosaurus (talk) 17:29, 28 January 2014 (UTC)

This thing on "(NH₄)₃PO₄ was sort of a chemical myth, so I converted an article that boasted of its import into one admitting that it is fragile and basically unimportant. In any case articles on "big boring salts" (BBS) often need attention. These BBSs include the alkali, alkaline earth, iron, and ammonium salts of sulfates, phosphates, nitrates, carbonates, hydroxides. These articles tend to collect all kinds of esoterica ("grandma's cleaning agent" type thing), which is not evil, but needs to be kept in check and described with some perspective. Petergans raised the point that many of these articles need some crystallography. I have tried to mention all of the hydrates for each of these materials. --Smokefoot (talk) 06:33, 28 January 2014 (UTC)

I am supporting what happened to ammonium phosphate. However Isn't the worklist historical? Some things out of scope do not make sense as they are major and important chemicals. But perhaps everything on that list should have importance at least mid. The worklist does not talk about importance ratings. The worklist only has 50 commodity chemicals, I think we can move on from that now! Graeme Bartlett (talk) 20:44, 29 January 2014 (UTC)

Resveratrol article

Like I stated at Misplaced Pages:WikiProject Pharmacology, "More eyes on the Resveratrol (edit | talk | history | protect | delete | links | watch | logs | views) article are needed. New editor Local4554 is repeatedly blanking material at the article without justifying his edits, and despite warnings not to do so." Flyer22 (talk) 18:47, 12 February 2014 (UTC)
