Facts

Interesting Facts
  • At room temperature Sodium metal is very soft as it can be chopped down into pieces with butter knife.
  • The most common compound of Sodium is NaCl (Salt).
  
  • 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
  • In some nuclear reactors sodium is used as a heat exchanger.
  • Compound of Sodium metals called Salt (Sodium chloride) is used in Food.
  
  • 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.
