Interesting Facts
- Seaborgium most stable isotope is Sg and it has 2.1 min of half- life.
- And other isotopes of Seaborgium have half-lives as short as 3 ms.
- 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.
