Interesting Facts
- Americium metal is produced by bombarding Plutonium with Neutrons.
- Americium metal was discovered as a by-product while testing an atomic bomb (Manhattan Project).
- 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.
