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.
  
  • Luster of Indium is bright in nature.
  • Reich and richer were looking for thallium in zinc metal and they discovered Indium metal.
