The Lecoq de Boisbaudran family was of considerable fortune until the revocation of the Edict of Nantes, after which much of their property was confiscated and sold. [6] Paul-Émile (Francois) Lecoq de Boisbaudran was a son of Paul Lecoq de Boisbaudran (1801–1870) and his wife Anne Louise. [5]
Discovered by the French chemist Paul-Émile Lecoq de Boisbaudran in 1875, [13] gallium is in group 13 of the periodic table and is similar to the other metals of the group (aluminium, indium, and thallium). Elemental gallium is a relatively soft, silvery metal at standard temperature and pressure. In its liquid state, it becomes silvery white.
In 1875, the Parisian chemist Paul Emile Lecoq de Boisbaudran used a spectroscope to discover a new metallic element. It was a silvery-white, soft metal with an atomic weight of 68, which he named gallium, after his native France.
Gallium was discovered by French scientist Paul-Émile Lecoq de Boisbaudran, who named it in honor of France ("Gallia" in Latin); allegations were later made that he had also named it for himself, as "gallus" is Latin for "le coq", but he denied that this had been his intention. [8]

French chemist Paul Émile Lecoq de Boisbaudran, while working with holmium oxide, separated dysprosium oxide from it in Paris in 1886. [22] [23] His procedure for isolating the dysprosium involved dissolving dysprosium oxide in acid, then adding ammonia to precipitate the hydroxide. He was only able to isolate dysprosium from its oxide after ...
Europium was first found in 1892 by Paul Émile Lecoq de Boisbaudran, who obtained basic fractions from samarium-gadolinium concentrates which had spectral lines not accounted for by samarium or gadolinium.
