Manganese - Wikipedia

Manganese is a chemical element with the symbol Mn and atomic number 25. It is not found as a free element in nature; [not verified in body] it is often found in minerals in combination with iron.Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels.. First isolated in 1774, manganese is mainly used in the production of steel.
