Interesting Facts
- Plutonium metal if obtain from ores of uranium metal.
- Plutonium metal is very sensitive to the change in atmospheric conditions like temperature and pressure.
- 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.
