Mineral Species sorted by the element Dy Dysprosium (original) (raw)

Dysprosium (Dy) Element Properties

Atomic Mass 162.5
Atomic Number 66
Name Origins Greek, dysprositos = "hard to obtain."
Year Discovered 1886
Discovery Credits Discovered by Paul-Emile Lecoq de Boisbaudran at Paris, France.
Remarks Reactive, hard, silvery metal of the rare earth group. Oxidized by oxygen, reacts rapidly with water, dissolves in acids. Used in alloys for making magnets.Diagnostic tests: There are no simple diagnostic tests to identify dysprosium. X-ray fluorescence spectroscopy is commonly employed to identify and analyze members of the Rare-Earth group elements.
