2 Facts
2.1 Interesting Facts
  • Naturally occurring minor elements include Cadmium.
  • Cadmium is released into atmosphere to control volcanic eruption and forest fires.
  • It is used for electroplating of Steel for corrosion resistance.
  • It can absorb neutrons and used in nuclear reactor to control atomic fission.
  • 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.

3 Uses
3.1 Uses & Benefits
  • It has very limited uses as it is a toxic metal and it can cause birth defects, cancer, etc.
  • Almost 80% of Cadmium metal is used in Nickel cadmium Batteries and now it is getting replaced with nickel hydride.
  • It is use for coinage and bullion.
  • Most of copper element is used in manufacturing electrical and electronic equipments such as wirings and components. It is also used in construction and industrial machine.
