Facts
Interesting Facts
  • Einsteinium is the transuranic element found in US.
  • Only 0.01 mg of Einsteinium was synthesized in 1961.
  
  • 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.
