Erbium is never found in nature as the free element. Erbium is found in the ores monazite sand [(Ce, La, etc.)PO 4 ] and bastnÂ°site [(Ce, La, etc.)(CO 3)F], ores containing small amounts of all the rare earth metals. It is difficult to separate from other rare earth elements.
A very hard, brittle, silvery-white transition metal of the platinum group, iridium is generally credited with being the second densest element (after osmium) based on measured density, although calculations involving the space lattices of the elements show that iridium is denser.he most stable of these is 192m2 Ir, which decays by isomeric transition with a half-life of 241 years, making it more stable than any of iridium's synthetic isotopes in their ground states. The least stable isomer is 190m3 Ir with a half-life of only 2 Âµs.
