2 Facts
2.1 Interesting Facts
  • Neodymium is not found free in nature, hence it is not a native metal.
  • Neodymium metal found in minerals like Monazite and Bastnaesite.
  • 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.
