Mineral Species sorted by the element Pt Platinum (original) (raw)

Platinum (Pt) Element Properties

Atomic Mass 195.08
Atomic Number 78
Name Origins Spanish, platina = "silver."
Year Discovered 1750
Discovery Credits Known to pre-Columbian South Americans and taken to Europe about 1790.
Remarks Silvery-white metal, lustrous, malleable, ductile. Unaffected by oxygen and water, only dissolves in aqua-regia and fused alkalis. Used in jewelry, drugs, catalysts, etc.Diagnostic tests: There are no simple chemical tests for platinum. 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.
