Information Sources: Some of the text in this entry was rewritten from Los Alamos National Laboratory - Manganese. Additional text was taken directly from USGS Manganese Statistics and Information, USGS Periodic Table - Manganese, from the Elements database 20001107 (via dict.org), Webster's Revised Unabridged Dictionary (1913) (via dict.org) and WordNet (r) 1.7 (via dict.org). Data for the table was obtained from the sources listed on the subject page and Wikipedia:WikiProject Elements but was reformatted and converted into SI units.

There is no section on the physical properties of metalic manganese!

i.e. different phases density, crystal structure, mp, bp...

very odd. if i have time one day i will try add some.

there are MANY cool facts:

two phases of solid manganese metal are VERY complex https://www.atomic-scale-physics.de/lattice/struk/mn.html

@Wikiskimmer: You can add this information yourself under Manganese#Physical_properties. –LaundryPizza03 (d c̄) 02:59, 23 December 2022 (UTC)[reply]

it's been a long time. i forget how to do all the wiki things! Wikiskimmmer (talk) 07:07, 23 December 2022 (UTC)[reply]

@Wikiskimmer:The difficult part is the content, the "wiki things" can be dealt with by many people. Its subject-expertise that Wikipedia most fervently seeks, not editing technique. --Smokefoot (talk) 13:56, 23 December 2022 (UTC)[reply]

ugh! writing takes so much effort. ok, here goes Wikiskimmmer (talk) 17:36, 23 December 2022 (UTC)[reply]

also, i TOTLY missed that there are a ton of physical facts on the box to the right! Wikiskimmmer (talk) 17:39, 23 December 2022 (UTC)[reply]

The allotropes are super interesting with their crazily complex unit cells. I just added a section on allotropes. Please add or repair as needed. –MadeOfAtoms (talk) 11:36, 30 January 2023 (UTC)[reply]

Added to wikidata.

This article is a GA from 2010. There are lots of uncited material which needs to be cited, and needs to be cleaned up (for example, the lead banner). I've gone ahead and added some {{Citation needed}} tags. ¹⁴¹ Pr 09:04, 4 February 2023 (UTC)[reply]

Discovery of Manganese. Whose fame?

Double sharp (greetings to Double sharp) gave the honor of the first discoverer to Kaim (1770)^[1] on Wikipedia. Others say that it was Scheele^[2] with his friend Gahn (1774). I understand that Kaim did it earlier, but the source implies his discovery was not fully confirmed, right? It turns out that Kaim was one of those who discovered manganese... What can we do?

@Tosha Langue: Thanks for prompting me to investigate this further! RSC credits Kaim too, and Venetskii in 1966 said there were grounds to believe he was first, though some details are missing. The Pergamon volume on group 7 says In 1770 J. G. Kaim heated pyrolusite with black flux and obtained a regulus, but it was not until 1774 that the great Swedish chemist, C. W. Scheele, realized that the ore and its extracts contained a new element. Although Scheele made this discovery he did not succeed in isolating the metal, and this was achieved by J. G. Gahn the same year. However in 2020 a historical study of Scheele and Bergman wrote It is possible that manganese had been prepared before Scheele’s studies. It is, for example, possible that Kaim prepared manganese in 1770 [and here Kaim's original work, which I can't consult, is cited], but his results are unverified and gained little recognition.

I think now that it's probably best to hedge Kaim's claim with a word like "possibly" or "probably". Double sharp (talk) 02:33, 20 November 2023 (UTC)[reply]
