It looks similar to platinum but is harder, more brittle, and much rarer. Upon heating it combines readily with oxygen. It is useful in hardening platinum and palladium as an alloy. Ruthenium is found among the fission outputs of uranium and plutonium in nuclear reactors. Ruthenium has four allotropic forms. The metal doesn't tarnish in air at normal temperatures and resists attack by many strong acids. RHODIUM Rhodium is a silvery white, soft, ductile, malleable metal. Its primary use is as an alloying agent for hardening platinum. It is not corroded or tarnished in the atmosphere at room temperature, and it is highly resisted to attack by acids. End
