[edit] 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.
[edit] Talk
Could anyone explain tome how Quantum numbers effect the shape, size and orientation of Mn?
Does anyone know how to remediate soil with high manganese content?
[edit] 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.
[edit] Potassium Permanganate
This is also known as an indicator for acid/base reactions.
- This belongs on the potassium permanganate page, not here, as it is not a major use. Also, I am not familiar with this use, I didn't think it changed colour with pH, other than to start decomposing at high pH values. Do you have a reference for this application?

In the 17th century it was founded by the chemist named kith glauber
[edit] Magnetic Properties
This entry contained quite a bit of erroneous information on the magnetic properties of manganese. Although manganese is well-known to be paramagnetic, it was listed in the entry as "nonmagnetic", so I corrected this in the entry. The only reason I found out about this is because one of my coworkers, relying on Wikipedia (as he should be able to), included manganese in an experiment that was incompatible with the presence of any paramagnetic material. Let this serve as an example of the fact that publishing erroneous information can have real world consequences. Biochemnick 23:29, 8 February 2007 (UTC)
- Thanks for fixing that! We do have to be vigilant. Walkerma 05:24, 9 February 2007 (UTC)
