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.
- X-ray Diffraction- different compounds of Berkelium metals are identified using it.
Commercial uses of Berkelium metal are not yet discovered.
