Rhenium (atomic number 75, symbol Re) is a metal with a silvery-white color, high density, and high melting point. Only platinum, osmium, and iridium have higher densities than rhenium. It is a transition metal that is solid at room temperature and has similar chemical properties to technetium and manganese. The metal was discovered in 1925 by Garl Berg, Walter Noddack, and Ida Tacke-Noddack. This is the last naturally occurring, non-radioactive, and stable chemical element to be isolated.
