gadolinium was named as such because it was named after the origin J Galotin
Gadolinium = Gd
gadolinium
It originates from the the Latin word "Gallia" which refers to France.
Gadolinium (Gd) is an element.
Gadolinium is sometimes referred to as Gd.
The atomic mass number of gadolinium is 157.25 g/mol.
Some compounds of gadolinium include gadolinium oxide, gadolinium chloride, and gadolinium nitrate. Gadolinium compounds are used in various applications, such as magnetic resonance imaging (MRI) contrast agents, in the production of specialized magnets, and in certain electronics and optical devices.
Gadolinium has 7 valence electrons.
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.
