Facts
Interesting Facts
- Luster of Indium is bright in nature.
- Reich and richer were looking for thallium in zinc metal and they discovered Indium metal.
- 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.
