Rhodium ,its cas register number is 7440-16-6. It is a chemical element and is one of the most expensive precious metals. It is not attacked by acids and its metal does not normally form an oxide, even when heated. The most stable radioisotopes are 101Rh with a half-life of 3.3 years, 102Rh with a half-life of 207 days, 102mRh with a half-life of 2.9 years, and 99Rh with a half-life of 16.1 days. The industrial extraction of Rhodium (CAS NO.7440-16-6) is complex as the metal occurs in ores mixed with other metals such as palladium, silver, platinum, and gold. It is also possible to extract rhodium from used nuclear fuel, which contains rhodium. Rhodium compounds can strongly stain human skin. If used in elemental form rather than as compounds, the metal is harmless. |
