Facts
Interesting Facts
  • 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.
  
  • Original name of Technetium was Masurium.
  • At the time of its discovery it found in sample of Molybdenum.
