2 Facts
2.1 Interesting Facts
  • Osmium metal does not oxidize in air unless it is heated.
  • But if it heated den it forms Osmium Tetroxide, which is highly toxic.
  • 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.

3 Uses
3.1 Uses & Benefits
  • Its has very limited uses and its alloys are very hard and are used in the manufacturing of pen tips, pivots, needles and electrical contacts.
  • It is also used as industrial catalyst to speed up the chemical reaction.
  • 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.
