2 Facts

2.1 Interesting Facts

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.

Osmium metal does not oxidize in air unless it is heated.
But if it heated den it forms Osmium Tetroxide, which is highly toxic.
