Facts
Interesting Facts
  • Plutonium metal if obtain from ores of uranium metal.
  • Plutonium metal is very sensitive to the change in atmospheric conditions like temperature and pressure.
  
  • Bismuth metal is soluble and reacts with concentrated nitric acid.
  • It oxides are used as a yellow pigment in paint. Bismuth chloride oxide BiClO gives a pearly texture to cosmetics.

Uses
Uses & Benefits
  • Plutonium was used in atomic bombs and still it is being used in various weapons and Ammunition industry.
  • It is also used in nuclear power plant as source of energy for space missions.
  
  • Tin and bismuth alloys have a very low melting point and hence it is used in fire detector and the fire extinguishers. It also used in electric solders and fuses.
