Soret, Jacques-Louis

Four rare-earth elements (yttrium, ytterbium, erbium, and terbium) have been named in honor of this village. A year later, the Swedish chemist Lars Fredrik Nilson (1840-1899), discovered another element in "erbia" and he named it scandium (Sc) in honor of Scandinavia. At the same time, Nilson s compatriot, the geologist and chemist Per Theodor Cleve (1840-1905) succeeded in resolving the "erbia" earths yet another step further, when he separated it into three components erbium, "holmium" (Flo) and thulium (Tm). The name "holmium" refers to Stockholm (Qeve s native city) and had been independently discovered by the Swiss chemists Marc Dela-fontame (1838-1911) and Jacques-Louis Soret (1827-1890), who had coined the metal element X on the basis of its absorption spectrum. 

The name is from the Latin Holmia for the city of Stockholm, the region where the original minerals were found. The discovery of holmium was part of the complex yttria rare-earths research. A new element was suggested by Jacques-Louis Soret (1827-1890) in 1878 and was named by Per Theodor Cleve (1840-1905) in 1880 its oxide was isolated in 1886 by Lecoq de Boisbaudran. The pure metal was isolated in 1911 by 0. Holmberg. It is a rare element and does not occur in pure form in nature. The silvery metal has unusual magnetic properties but no current commercial uses. 

Swiss scientists Jacques-Louis Soret and Marc Delafontaine discover the element holmium, which also is independently discovered by Swedish chemist Per Theodor Cleve. Swiss chemist Jean-Charles de Marignac discovers the element ytterbium.
