Talk:Manganese

Manganese was one of the Natural sciences good articles, but it has been removed from the list. There are suggestions below for improving the article to meet the good article criteria. Once these issues have been addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake.

Article changed note

Article changed over to new Wikipedia:WikiProject Elements format by Dwmyers 22:00 Feb 24, 2003 (UTC) and Mkweise. Elementbox converted 14:44, 2 July 2005 by Femto (previous revision was that of 12:16, 27 May 2005). 27 May 2005

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.

Oxidation States

This was written poorly.

The most common oxidation states of manganese are +2, +3, +4, +6 and +7, though oxidation states from +1 to +7 are observed.

The only oxidation states missing are +1 and +5, so why not -

The most common oxidation states of manganese are +2, +3, +4, +6 and +7, but oxidation states of +1 and +5 are also observed.

Re-rate?

I think this is getting to be close to A class. I'd like to see it as a Featured Article. S B H arris

Suggestions moving forward to Featured article review

This article is one of the best articles I've read in reviewing GA nominees, and I find it is mostly ready for FA review as it stands. --Tea with toast (talk) 17:52, 7 March 2010 (UTC)[reply]

A few minor changes might be helpful:

In the "Occurrences and production" section, there are photos of manganese ore and Psilomanganese (manganese ore); however, I could not find what distinguishes these two different ores in the text.
I find the third paragraph in "Occurrences and production" to be a bit confusing. Also, the term "ferromanganese" is first occurs there but the subsequent paragraph suggests that ferromangaese is produced, not mined. I would create a new paragraph (or expand the second paragraph) describing the different types of ore.

Further comments

The phrase "undergo a sort of resettlement" is used twice; once in the intro and the other in Geology. I recommend finding a different term that wouldn't cause repetition. I also went ahead an made a grammar fix. Codyorb (talk) 14:40, 22 August 2020 (UTC)[reply]

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]

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]
