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.
- Yttrium Metal is highly toxic.
- Yttrium Metal is highly reactive in nature hence not found free in nature.

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.
- Yttrium metal is used in different alloys, as it increases the strength of aluminum Magnesium alloy. It is used for radar microwave filter.
-
It is also used as a catalyst in ethene polymerisation.
