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.
  
  • Molybdenum is highly reactive metal, hence not found free in nature .
  • Till 18th century Molybdenum element were often mistaken as a carbon or Lead.

Uses

Uses & Benefits
  • 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.
  
  • Its alloys are used to make engine parts, drills, saw blade, etc.
  • Lubricant additive made up of Molybdenum disulfide is commonly used in the industry. It is also used as a catalyst.
