Interesting Facts
- Copper rarely found in its pure form in nature.
- Copper Sulfate is mostly used in agricultural poison and as an algicide in water purification system.
- 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.
