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.
  
  • Iron is not always magnetic in nature, its allotrope are ferromagnetic and the B allotrope is nonmagnetic.
  • The blood consists Iron in hemoglobin molecules to transfer Oxygen in the body.

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.
  
  • Iron metal alloy steel is used in the application of civil engineering and manufacturing.
  • Alloys of iron with nickel, vanadium, chromium, tungsten and manganese have very useful properties.
