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.
  
  • Palladium alloys are used for Jewelry contains (95% Palladium and 5% Ruthenium)
  • In the late 1800s, Palladium metal used have more economical value than the Platinum metal.
  • Palladium element is known as a good catalyst
