Facts
Interesting Facts
  • Thorium metal is used as an alternate option over Uranium for nuclear fuel.
  • Thorium metals appearance (silvery white, soft) is somewhat similar to Lead metal.
  
  • 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.
