Erbium (Er ) by %

**Erbium (Er) Element Properties**
Atomic Mass	167.26
Atomic Number	68
Name Origins	Named after Ytterby, Sweden.
Year Discovered	1842
Discovery Credits	Discovered by C. G. Mosander at Stockholm, Sweden.
Remarks	Silver-gray metal of the rare earth group. slowly tarnishes in air, slowly reacts with water, dissolves in acids. Used in infrared absorbing glass, alloys with titanium. Diagnostic tests: There are no simple diagnostic tests to identify erbium. X-ray fluorescence spectroscopy is commonly employed to identify and analyze members of the Rare-Earth group elements.
