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 ; 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 region of Magnesia in Greece, which also gave its name to magnesium and the iron ore magnetite. By the mid-18th century, Sw…
