Interesting Facts
- Rhodium is the rarest element out of all non-radioactive metals on the earth .
- Rhodium is one of the most durable and hard metal, which also have high reflectance.
- Manganese is an essential trace element in all forms of life.
- Manganese metal oxidizes very easily, but it does not fuse that easily.

Uses & Benefits
- Rhodium metal is mainly used in catalytic converters for cars as it reduces nitrogen oxides in exhaust gases.
- It is used as an industrial catalyst for nitric acid, acetic acid, hydrogenation reaction, etc.
- This metal is very brittle hence it mostly not used as a pure metal, but its alloys are very useful
- Its alloy Manganese steel is extremely strong and used in railway tracks, safes, prison bars and riffle barrels.
