White gold is often plated with a thin rhodium layer to improve its appearance while sterling silver is often rhodium-plated for tarnish resistance. Rhodium detectors are used in nuclear reactors to measure the neutron flux level.t has only one naturally occurring isotope, 103 Rh. 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.
Radium is a silvery-white metal. It is highly radioactive and its decay product, radon gas, is also radioactive. One result of radiumâs intense radioactivity is that the metal and its compounds glow in the dark. When it is exposed to air, it reacts with nitrogen to quickly form a black coating of radium nitride.iscovery of Radium. Radium was discovered in 1898 in Paris, by Marie S. Curie and her husband Pierre in pitchblende (mainly uranium dioxide, UO 2).
