Facts

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