Facts
Interesting Facts
Flerovium is named after the Flerov Laboratory of Nuclear Reactions.  
  • Chromium is highly reactive, hence it is not found free in nature.
  • Ores of Chromites mineral are the major source of Chromium metal.
  • Almost 90% leather tanning is done with the help of chromium.
