Iridium is a chemical element with the symbol Ir and atomic number 77. A very hard, brittle, silverywhite transition metal of the platinum group, iridium is the seconddensest metal (after osmium) with a density of g/cm 3 as defined by experimental Xray crystallography. At room temperature and standard atmospheric pressure, iridium has a calculated density g/cm 3 higher than ...
