Facts
Interesting Facts
  • Platinum is the rarest metal from the Precious metal categories..
  • Commercially Platinum is produced as a byproduct in ores of nickel.
  
  • Iron is not always magnetic in nature, its allotrope are ferromagnetic and the B allotrope is nonmagnetic.
  • The blood consists Iron in hemoglobin molecules to transfer Oxygen in the body.
