Description
Iridium is a chemical element with the symbol Ir and atomic number 77. A very hard, brittle, silvery- white transition metal of the platinum group, iridium is considered to be the second-densest metal (after osmium) with a density of 22.56 g/cm 3 as defined by experimental X-ray crystallography.
Properties
Iridium is less common than gold or platinum. In nature, it occurs elementally in the form of small grains or in the accompaniment of platinum. With osmium, it forms two naturally occurring minerals.
