Mineral Species containing Beryllium (Be)

Element Properties, Isotopic Compositions for Beryllium

**Beryllium (Be) Element Properties**
Atomic Mass	9.01218
Atomic Number	4
Name Origins	Greek, beryllos = "beryl."
Year Discovered	1797
Discovery Credits	N. L. Vauquerlin at Paris, France. Isolated in 1828 by R. Wohler at Berlin, Germany, and independently by A. A. B Bussy at Paris, France.
Remarks	Silvery-white, lustrous, relatively soft metal, obtained by the electrolysis of fused BeCl₂. Unaffected by air or water even at red heat. Used in alloys with copper and nickel, and imparts excellent electrical and thermal conductivities. Copper alloy used to make spark-proof tools. Diagnostic tests: The majority of beryllium-bearing minerals are silicates or phosphates. There are no simple chemical tests to determine Be. Atomic Emission spectroscopy and atomic adsorption spectroscopy are commonly employed for the detection of beryllium.
