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.
  
- Zinc metal found (obtain) in many forms like granules, foil, dust and in a powder form.
- After iron, Zinc metal the second most abundant element in the earth crust.

Uses & Benefits
- 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.
  
- It has corrosion resistance and hence it is used to plate other metals.
- Its alloys are very useful; Nichrome alloy is used in the hot coil of toasters and electric oven.
