Facts
Interesting Facts
  • Metal dust of Lutetium element is highly explosive.
  • Lutetium metal is corrosion resistance and acts stable in air.
  
  • Molybdenum is highly reactive metal, hence not found free in nature .
  • Till 18th century Molybdenum element were often mistaken as a carbon or Lead.
