Facts

Interesting Facts
  • Bohrium metal is also known as Unnilseptium (Uns) and Nielsbohrium (Ns).
  
  • 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.
