2 Facts
2.1 Interesting Facts
  • Heat capacity of Lithium is very high.
  • Lithium inflammable and highly explosive metal, hence it has to be stored properly.
  • Hafnium metal is highly reactive, hence not found free in nature.
  • Hafnium metal as predicated after Mendeleev finished his periodic table.

3 Uses
3.1 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.
  • It has an ability to absorb neutrons and hence it is used to make control rods in nuclear submarines. And this metal is also used in Plasma welding torches.
  • It alloys with iron, titanium and niobium are very useful.
