Manganese

Manganese Element:

Manganese is a chemical element and it is a member of group 7 and period 4 in the periodic table. The atomic number of manganese is 25 and it is indicated by symbol is Mn. Manganese is found in minerals in combination with iron and it is not found as a free element in nature. Mn has 18 radioisotopes. 52Mn, 53Mn, 54Mn, 55Mn are the most stable isotopes. Mn is hard and very brittle, difficult to fuse, but easy to oxidize.

Uses of Manganese Element:

  • Mn is too brittle to be of much use as a pure metal. It is used in alloys, such as steel.
  • Manganese steel is used for railway tracks, prison bars and rifle barrels.
  • Manganese sulphate is used to make a fungicide.
  • Mn is also used to make fertilisers and ceramics
  • Manganese(II) oxide is used in quantitative analysis
