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. Historically, manganese is named for pyrolusite and other black minerals from the ...
