Rhodium

Mary Ann Waxler

Rhodium was discovered by William Hyde Wollaston, an English chemist, in 1804.The first rhodium was rose colored so it was named after the Greek word for rose, rhodon.

Rhodium is usually obtained as a by-product of mining and refining platinum. It’s used to make electrical contacts, in jewelry and catalytic converters. Its main use is as an alloying agent in other materials such as platinum and palladium. Rhodium is the rarest of all non-radioactive metals on Earth.
