Manganese is a silvery-gray metal that resembles iron. It is hard and very brittle, difficult to fuse, but easy to oxidize. Manganese metal and its common ions are paramagnetic. Manganese tarnishes slowly in the air and oxidizes ("rusts") like iron in water containing dissolved oxygen. The two main manganese minerals are pyrolusite (MnO2 ...
