2 Facts
2.1 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.
  • The main source of Cobalt is as a by-product of copper and nickel metal mining.
  • Cobalt metal can be obtained from other elements like Oxygen, Sulfur and Arsenic.
  • It s also used in electroplating process as it exhibits anti cession properties.

3 Uses
3.1 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.
  • Its alloys with aluminum and nickel are used to make powerful magnets.
  • Few other alloys exhibit high-temperature strength and hence they are used in Turbines of Jet and Gas engine.
