What is rhodium do you know what the cowboy did with the bull at the rodeo he rhodium get it rode-him but wait, rhodium isn't only a punch line, it's one of the elements on the periodic table rhodium, (abbreviated rh), is a rare, silvery-white metal that is a solid at room temperature and has 45 protons in its nucleus. Near the base of the duluth complex, which is a group of igneous intrusions in minnesota introduction the platinum-group elements (pges)—platinum, palladium, rhodium, ruthenium, iridium, and osmium—are chemical elements that have similar physical and chemical properties and tend to occur together in nature.
Shortly after palladium (1802), rhodium was discovered in 1804 in crude platinum from south america by the english chemist william hyde wollaston ( 1766-1828) (note) from his sample crude platinum he removed the platinum and palladium and was left with a dark red powder this proved to be the double chloride of.
