Facts
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.
  
  • Beryllium is best anti corrosion metal.
  • Beryllium is the lightest metal and still it is stronger than steel.
  • It also finds various applications in Nuclear reactors as a reflector.
