Gadolinium is a chemical element; ... Gadolinium was discovered in 1880 by Jean Charles de Marignac, who detected its oxide by using spectroscopy.
In 1880 he found gadolinium and samarium in the samarskite earths. [12] The family grave. In 1858, he pointed out the isomorphism of the fluostannates and the fluosilicates, thus settling the then vexed question of the composition of silicic acid. [10] This research helped him to confirm the atomic weights of zirconium and titanium. [9]
Johan Gadolin (5 June 1760 – 15 August 1852) [1] was a Finnish chemist, physicist and mineralogist.Gadolin discovered a "new earth" containing the first rare-earth compound yttrium, which was later determined to be a chemical element.
The first rare-earth mineral discovered (1787) was gadolinite, a black mineral composed of cerium, yttrium, iron, silicon, ... Europium, gadolinium, and terbium were ...
helium: named for the Sun where it was discovered by spectral analysis, being associated with the deity Helios, iridium: named for the Greek goddess Iris, tellurium: named for the Roman goddess of the earth, Tellus Mater, niobium: named for Niobe, a character of Greek mythology, vanadium: named for Vanadis, another name for Norse goddess Freyja,
The rare earth gadolinium was also named after him. However, gadolinite does not contain more than trace amounts of gadolinium. ... In order of date discovered, the ...
These rare-earth oxides are used as tracers to determine which parts of a watershed are eroding. Clockwise from top center: praseodymium, cerium, lanthanum, neodymium, samarium, and gadolinium. Earths were defined by the Ancient Greeks as "materials that could not be changed further by the sources of heat then available". [1]
Gadolinium(III) oxide (archaically gadolinia) is an inorganic compound with the formula Gd 2 O 3. It is one of the most commonly available forms of the rare-earth element gadolinium , derivatives, of which are potential contrast agents for magnetic resonance imaging .
