Facts
Interesting Facts
  • Neodymium is not found free in nature, hence it is not a native metal.
  • Neodymium metal found in minerals like Monazite and Bastnaesite.
  
  • Luster of Indium is bright in nature.
  • Reich and richer were looking for thallium in zinc metal and they discovered Indium metal.
