Facts
Interesting Facts
  • Tungsten element has the second highest melting point.
  • Pure tungsten can easily cut down with the help of hacksaw.
  
  • 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.
