Mineral Species sorted by the element In Indium (original) (raw)

Indium (In) Element Properties

Atomic Mass 114.82
Atomic Number 49
Name Origins Named after the indigo line in its spectrum.
Year Discovered 1863
Discovery Credits Discovered by Ferdinand Reich and Hieronymous Richter at Frieberg, Germany.
Remarks Soft, silvery-white metal. Stable in air and with water, dissolves in acids. Used in low melting alloys in safety devices. Semiconductor uses as InAs and InSb in transistors, thermistors, etc.Diagnostic tests: There are no simple chemical tests for indium. Atomic Absorption Spectroscopy is used for quantitative analysis and Energy Dispersive Analysis of X-rays (EDAX) is used for qualitative analysis. The flame test for Indium may show a blue color.
