Facts
Interesting Facts
  • In the list of most abundant element Tin is ranked 49th.
  • Tin metal does not react with water as well as does not corrode in it.
  
  • Molybdenum is highly reactive metal, hence not found free in nature .
  • Till 18th century Molybdenum element were often mistaken as a carbon or Lead.
