Metals form a giant structure (like ionic compounds and giant molecules). In the picture below the red balls represent metal ions. The blue lines represent delocalised electrons in the outer shell of the metal ions. Delocalised means that the electrons are not attached to one particular ion. The delocalised electrons between the positive metal ions

Iridium - Wikipedia

Iridium is a chemical element with the syol Ir and atomic nuer 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.However, at room temperature and standard atmospheric pressure, iridium has been calculated to have a
