Interesting Facts
- 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.
  
- Aluminum’s abundance percentage is more as it is found in more than 260 minerals.
- Pure Aluminum always reacts with oxygen rapidly.
- It is a good conductor of heat and electricity and used in transmission lines.
