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.
- Neodymium is not found free in nature, hence it is not a native metal.
- Neodymium metal found in minerals like Monazite and Bastnaesite.
