2 Facts
2.1 Interesting Facts
  • Barium oxidizes very easily in the air.
  • All toxic compounds of Barium can easily dissolve in water.
  • Barium carbonate is used to produce a Rat poison and its other compound Barium nitrate is used in fireworks to produce green color.
  • Manganese is an essential trace element in all forms of life.
  • Manganese metal oxidizes very easily, but it does not fuse that easily.

3 Uses
3.1 Uses & Benefits
  • It is sued in chemical paint manufacturing and glass manufacturing.
  • Compounds of this metal are toxic; but still the barium sulfate is insoluble and given to patients suffering from digestive disorder.
  • This metal is very brittle hence it mostly not used as a pure metal, but its alloys are very useful
  • Its alloy Manganese steel is extremely strong and used in railway tracks, safes, prison bars and riffle barrels.
