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.
  
  • Hassium metals rate of decay is very high.
  • Hassium metals 1st sample was synthesized through a nuclear reaction.
