Facts
Interesting Facts
  • Americium metal is produced by bombarding Plutonium with Neutrons.
  • Americium metal was discovered as a by-product while testing an atomic bomb (Manhattan Project).
  
  • 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.
