Mineral Species containing Rhodium (Rh)

Element Properties, Isotopic Compositions for Rhodium

**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.
