Description: Rhodium is a chemical element with symbol Rh and atomic number 45. It is a rare, silvery-white, hard, corrosion-resistant transition metal and a member of the platinum group metals (PGMs). Rhodium is found in platinum or nickel ores and is primarily mined in South Africa and Russia. Its main use is in catalytic converters for automobiles, where it helps reduce nitrogen oxide emissions. It is also used in jewelry, electrical contacts, and as a catalyst in various chemical reactions. Rhodium is one of the rarest and most valuable precious metals, with prices often exceeding those of gold and platinum. The metal was discovered in 1803 by William Hyde Wollaston in England. Rhodium is traded as a commodity on various exchanges, and its price is influenced by supply constraints, automotive demand, and industrial usage.
