It's just one The natural way happening isotope, which can be 103Rh. The natural way taking place rhodium is frequently found being a absolutely free steel or being an alloy with very similar metals and rarely being a chemical compound in minerals for example bowieite and rhodplumsite. It is one of the rarest and look at here most useful treasured metals.
Rhodium-plated sterling silver is sterling silver coated with a thin layer of rhodium to generate jewellery. Rhodium increases the intrinsic value and endurance of sterling silver.
