Rhodium (Rh) is a metallic chemical element with atomic number 45. The only stable and naturally occurring rhodium isotope is 103Rh, with 45 protons and 58 neutrons.

Just like palladium and platinum, a major industrial use of rhodium is in cataylic converters, to clean up exhaust gases in cars. It is also sometimes used in jewellery.
