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.
  
  • Thulium metal can resist corrosion due to dry air .
  • Only Tm-169 isotope of Thulium metal occur naturally.
