Legend

Name origin:	Named for the Swedish village of Ytterby.
Description:	Silvery, lustrous, malleable, and ductile metal.
Discovered by:	Jean de Marignac
Year:	1878
Place:	Switzerland
Sources:	Found in minerals such as yttria, monazite, gadolinite, and xenotime. Monazite is often 50% rare earth by weight and typically 0.03% ytterbium.
Use(s):	Used in metallurgical and chemical experiments.
