Facts
Interesting Facts
  • Heat capacity of Lithium is very high.
  • Lithium inflammable and highly explosive metal, hence it has to be stored properly.
  
  • Palladium alloys are used for Jewelry contains (95% Palladium and 5% Ruthenium)
  • In the late 1800s, Palladium metal used have more economical value than the Platinum metal.
  • Palladium element is known as a good catalyst
