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.
  
  • Zinc metal found (obtain) in many forms like granules, foil, dust and in a powder form.
  • The leading producers of Zinc metal are Australia, Canada, China, U.S.A and Peru.
