Facts
Interesting Facts
  • 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
  
  • Yttrium Metal is highly toxic.
  • Yttrium Metal is highly reactive in nature hence not found free in nature.
