Facts
Interesting Facts
  • At room temperature Sodium metal is very soft as it can be chopped down into pieces with butter knife.
  • The most common compound of Sodium is NaCl (Salt).
  
  • Vanadium is a highly reactive metal, hence it is not found free in nature.
  • Vanadium can be found in almost 65 different types of minerals.

Uses
Uses & Benefits
  • In some nuclear reactors sodium is used as a heat exchanger.
  • Compound of Sodium metals called Salt (Sodium chloride) is used in Food.
  
  • Its ally with steel is used very tough and hence it is used in armor plates, axles, piston rods, tools and crankshafts.
  • Its oxide is used as pigments for glass and ceramics.
