Then comes iridium, the rarest metal on earth,

Iridium is extremely inert chemically, resisting even the action of aqua regia. In its chemical compounds it forms tetravalent and trivalent salts. It is an extremely rare metal, ranking 77th in order of abundance of the elements in the crust of the earth. The atomic weight of iridium is 192.22. It melts at about 2410° C (about 4370° F) and boils at about 4130° C (about 7466° F), and has a specific gravity of 22.6. Iridium and osmium are considered the most dense elements.
