Facts
Interesting Facts
  • Tantalum metal is known as corrosion resistance.
  • Tantalum metal can easily fabricated and It is a good conductor of heat and electricity.
  
  • 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.
