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.
  
  • Beryllium is best anti corrosion metal.
  • Beryllium is the lightest metal and still it is stronger than steel.
  • It also finds various applications in Nuclear reactors as a reflector.
