Rhodium (Rh) Element Properties

Atomic Mass 102.9055
Atomic Number 45
Name Origins Greek, rhodon = "rose"
Year Discovered 1803
Discovery Credits W. H. Wollaston at London, UK.
Remarks Rare, lustrous, silvery, hard mental of the platinum group. Stable in air up to 875 K. Inert to all acids, attacked by fused alkalis. Used as a catalyst.Diagnostic tests: There are no simple chemical tests for rhodium. The element is usually found as an alloy or a sulfide mineral with other platinum group metals. Atomic Absorption Spectroscopy is used for quantitative analysis and Energy Dispersive Analysis of X-rays (EDAX) is used for qualitative analysis.
