Legend

Name origin:	Greek: kadmeia (ancient name for calamine (zinc oxide)).
Description:	Soft, malleable, blue-white metal.
Discovered by:	Fredrich Stromeyer
Year:	1817
Place:	Germany
Sources:	Obtained as a by product of zinc refining.
Use(s):	Used in nickel-cadmium batteries. Also in electroplating steel and in the manufacture of berings. Its compounds are found in paint pigments and a wide variety of intense colors. Boiling cadmium gives off a weird, yellow-colored vapor that is poisono
