Facts
Interesting Facts
  • Niobium metal was used to get called Columbium in past.
  • Niobium metal found freely in nature (abundance).
  
  • 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.
