Geskiendenis
Ytterbium was discovered by the Swiss chemist Jean Charles Galissard de Marignac in the year 1878.

In 1907, in Paris, George Urbain separated ytterbia into two constituents.

Ytterbium metal was first made in 1937 by Klemm and Bonner by heating ytterbium chloride and potassium together.

A relatively pure sample of the metal was obtained only in 1953.

Toepassings
Ytterbium fiber laser amplifiers are used in marking and engraving.

Ytterbium compounds are also used as catalysts in the organic chemical industry.

Ytterbium can be used as a dopant to help improve the grain refinement, strength, and other mechanical properties of stainless steel.
Ytterbium is considered to be moderately toxic
