Jean Charles Galissard de Marignac, a Swiss chemist, named samarium in 1853.
Ytterbium was discovered by Jean Charles Galissard de Marignac in 1878. He heated erbium nitrate until it decomposed and then extracted the residue, which contained an unknown white powder that he named ytterbium oxide. The pure metal was not produced until 1953. The element is named after Ytterby, a village in Sweden. Four elements are named after this town, the others being yttrium, terbium, and erbium.
Jean de Marignac is the one credited with discovering the element ytterbium. He found this element in Switzerland in 1878.
Gadolinium is named from the mineral gadolinite, in turn named forFinnish chemist and geologist Johan Gadolin.[3] In 1880, the Swisschemist Jean Charles Galissard de Marignac observed the spectroscopic lines from gadolinium in samples of gadolinite (which actually contains relatively little gadolinium, but enough to show a spectrum) and in the separate mineral cerite. The latter mineral proved to contain far more of the element with the new spectral line. De Marignac eventually separated a mineral oxide from cerite, which he realized was the oxide of this new element. He named the oxide "gadolinia". Because he realized that "gadolinia" was the oxide of a new element, he is credited with discovery of gadolinium. The French chemistPaul Émile Lecoq de Boisbaudran carried out the separation of gadolinium metal from gadolinia in 1886.
