Facts
Interesting Facts
  • Osmium metal does not oxidize in air unless it is heated.
  • But if it heated den it forms Osmium Tetroxide, which is highly toxic.
  
  • Major mining countries of Uranium include Russia, Australia, Namibia, Canada and Niger and total 33% Uranium are mine in Kazakhstan.
