    • n rhodium Chemical symbol, Rh; atomic weight, 103 (Jörgensen). A metal discovered in the beginning of the nineteenth century by Wollaston, associated with palladium in the ore of platinum. Rhodium fuses in the flame of the oxyhydrogen blowpipe, but with greater difficulty than platinum. When fused it is grayish-white, resembling aluminium in luster and color, and has a specific gravity of 12.1. When pure it is almost insoluble in acids, but if in the state of an alloy it is dissolved by aqua regia. Of all the metals of the platinum group rhodium is the one most easily attacked by chlorin.
