Facts
Interesting Facts
  • Heat capacity of Lithium is very high.
  • Lithium inflammable and highly explosive metal, hence it has to be stored properly.
  
  • Osmium metal does not oxidize in air unless it is heated.
  • But if it heated den it forms Osmium Tetroxide, which is highly toxic.

Uses
Uses & Benefits
  • The main usage of Lithium is manufacturing rechargeable batteries for electronic equipment and gadgets.
  • it is also used in manufacturing non-rechargeable batteries.
  
  • 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.
