Facts
Interesting Facts
  • Gadolinium is not found free in nature, hence it is not a native metal.
  • Gadolinium metal found in minerals like Monazite and Bastnaesite.
  
  • Vanadium is a highly reactive metal, hence it is not found free in nature.
  • Vanadium can be found in almost 65 different types of minerals.
