Interesting Facts
- 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.
- Zinc metal found (obtain) in many forms like granules, foil, dust and in a powder form.
- After iron, Zinc metal the second most abundant element in the earth crust.

Uses & Benefits
- It is used to harden the steel and produces a stainless steel and other various alloys.
- It is also used to give proper finish to polished mirrors. Its chromium plates are used in bathroom fittings.
- It has corrosion resistance and hence it is used to plate other metals.
- Its alloys are very useful; Nichrome alloy is used in the hot coil of toasters and electric oven.
