Mineral Species containing Ytterbium (Yb)

Element Properties, Isotopic Compositions for Ytterbium

**Ytterbium (Yb) Element Properties**
Atomic Mass	173.04
Atomic Number	70
Name Origins	Named after Ytterby, Sweden.
Year Discovered	1878
Discovery Credits	Discovered by J. C. G. De Marignac at Geneva, Switzerland.
Remarks	Soft, sivery-white metal of the lanthanide (rare earth) group. Slowly oxidized by air, reacts with water. Some use in stress gauges. Diagnostic tests: There are no simple diagnostic tests to identify ytterbium. X-ray fluorescence spectroscopy is commonly employed to identify and analyze members of the Rare-Earth group elements.
