Gadolinium (Gd ) by %

**Gadolinium (Gd) Element Properties**
Atomic Mass	157.25
Atomic Number	64
Name Origins	Named after J. Gadolin, a Finnish chemist.
Year Discovered	1880
Discovery Credits	Discovered by J. C. Galissard de Marignac at Geneva, Switzerland. Isolated in 1886 by P. E. Lecoq de Boisbaudran at Paris, France.
Remarks	Silvery-white metal of rare earth group. Reacts slowly with oxygen and water, dissolves in acids. Used in magnets, electronics, neutron radiography, and alloys, with iron for magneto-optic recording devices. Diagnostic tests: There are no simple diagnostic tests to identify gadolinium. X-ray fluorescence spectroscopy is commonly employed to identify and analyze members of the Rare-Earth group elements.
