Facts

Interesting Facts
  • Neodymium is not found free in nature, hence it is not a native metal.
  • Neodymium metal found in minerals like Monazite and Bastnaesite.
  
  • 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.
