Rhodium does not appear naturally, tending to be found with other platinum group metals. It is a hard, lustrous, silvery coloured metal which is stable in air. Rhodium is inert to all acids but is attacked by fused alkalis. The metal has high thermal and electrical conductivities and is alloyed with platinum to form the positive wire of a Pt/Rh - P
