Mineral Species sorted by the element Lu Lutetium (original) (raw)

Lutetium (Lu) Element Properties

Atomic Mass 174.967
Atomic Number 71
Name Origins From the Latin, Lutetia = "Paris."
Year Discovered 1907
Discovery Credits Discovered by G. Urnain at Paris, France, and independently by C. James at the University of New Hampshire, USA.
Remarks Hardest, densest, and one of the rarest of the lanthanide metals. Little used except in research.Diagnostic tests: There are no simple diagnostic tests to identify lutetium. X-ray fluorescence spectroscopy is commonly employed to identify and analyze members of the Rare-Earth group elements.
