Description --------------------------------------------------------------------------------------------------------------------The iridium atom has a radius of 136 pm and a Van der Waals radius of 202 pm. Iridium was discovered and first isolated by Smithson Tennant in 1803. In its elemental form, Iridium has a silvery white appearance. Iridium is a member of theplatinumgroup ofmetals.Elemental IridiumIt is the most corrosion resistant metal known and is the second-densest element (afterosmium). It will not react with any acid and can only be attacked by certain moltensalts, such as moltensodium chloride. Iridium is found as an uncombined element and in iridium-osmiumalloys. Iridium's name is derived from the Greek goddess Iris, personification of the rainbow, on account of the striking and diverse colors of its salts.
