Mineral Species sorted by the element Sm Samarium

Samarium (Sm ) by %

**Samarium (Sm) Element Properties**
Atomic Mass	150.36
Atomic Number	62
Name Origins	Named after the mineral Samarskite.
Year Discovered	1879
Discovery Credits	Discovered by P. E. Lecoq de Boisbaudran at Paris, France.
Remarks	Silvery white metal of the lanthanide group. Relatively stable in dry air but in moist air an oxide coating forms. Used in permanent magnets, organic reagents, special glass, catalysts, ceramics, and electronics. Diagnostic tests: There are no simple diagnostic tests to identify Samarium. X-ray fluorescence spectroscopy is commonly employed to identify and analyze members of the Rare-Earth group elements.
