1 Summary
1.1 Definition and properties
Mn is the symbol of manganese, which is a chemical element in the VIIB group of the periodic table with an atomic number of 25. Its density is 7.43 g?cm?3. The melting point and boiling point of manganese are 1519 K (1246°C or 2275°F) and 2334 K (2061°C or 3742°F) respectively. Manganese is a silvery-gray metal that resembles iron. It is hard and very brittle, difficult to fuse, but easy to oxidize. Manganese is reactive when pure, and as a powder it will burn in oxygen. It reacts with water (rusting like iron) and dissolves in dilute acids. It is an important trace element which is essential for all species and is widely distributed in soil and oceans. As the 12th most abundant element in the Earth’s crust, it is widely used in steel, alloys, agriculture, batteries and chemicals.
