Mineral Species sorted by the element Eu Europium (original) (raw)

Europium (Eu) Element Properties

Atomic Mass 151.965
Atomic Number 63
Name Origins Named after Europe.
Year Discovered 1901
Discovery Credits Discovered by E. A. Demarcay at Paris, France.
Remarks Rare, and most reactive for the rare earth metals. Soft, silvery metal which reacts quickly with oxygen and water. Little used. Some used in thin-film superconductor alloy.Diagnostic tests: There are no simple diagnostic tests to identify europium. X-ray fluorescence spectroscopy is commonly employed to identify and analyze members of the Rare-Earth group elements.
