the platinum group. It has the chemical symbol Rh and atomic number 45. It is composed of only one naturally occurring isotope, 103Rh.
Naturally occurring rhodium is usually found as the free metal, alloyed with similar metals, and rarely as a chemical compound in minerals such as bowieite and rhodplumsite. It is one of the rarest and most valuable precious metals.
Rhodium is a so-called noble metal, resistant to corrosion, found in platinumor nickel ores together with the other members of the platinum group metals. It was discovered in 1803 by William Hyde Wollaston in one such ore, and named for the rose color of one of its chlorine compounds, produced after it reacted with the powerful acid mixture aqua regia.
