Facts

Interesting Facts
  • At room temperature mercury is found in a liquid state.
  • A coin of pound or rupees floats in mercury.
  • Because of its low melting point and boiling point it is used in thermometers.
  
  • 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).

Uses

Uses & Benefits
  • It is a liquid metal at room temperature, but it is a toxic heavy metal and hence many uses of mercury are under review or phased out.
  • It is manly used as a catalysts in chemical industry.
  
  • In some nuclear reactors sodium is used as a heat exchanger.
  • Compound of Sodium metals called Salt (Sodium chloride) is used in Food.
