Manganese

Silver-white, very brittle heavy metal or element (Mn), which is similar to iron in some properties. It does not occur in nature as an element, but only in the form of compounds. These include manganite, manganese dioxide (with oxygen), manganite and iron ore (with iron). Manganese is an essential trace element that is indispensable for various biochemical processes and enzyme functions in living organisms.
