Mineral Species containing Rhenium (Re)

Element Properties, Isotopic Compositions for Rhenium

**Rhenium (Re) Element Properties**
Atomic Mass	186.207
Atomic Number	75
Name Origins	After the Rhine river.
Year Discovered	1925
Discovery Credits	W. Noddack, Ida Tacke, and O. Berg in Berlin, Germany.
Remarks	Silvery metal, usually obtained as gray powder. Resists corrosion and oxidation but slowly tarnishes in moist air. Dissolves in nitric and sulfuric acids. Used in filaments, thermistors, and catalysts. Diagnostic tests: There are no simple chemical tests for rhenium. 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.
