Paul Émile (François) Lecoq de Boisbaudran ( April 18, 1838 - May 28, 1912) was a French chemistborn in Cognac. In 1858 he joined the family wine-making business, but a year later was working as a chemist. In 1874 he wrote Spectres lumineux, spectres prismatiques, et en longeurs d'ondes destines aux recherche de chimie minerale, which was published in Paris by Gauthier-Villars and was one of the first descriptions of the new science of spectroscopy developed by Kirchhoff. In 1875 he used this method to discover the element gallium, which he named after the LatinAlternative meanings: See Latin (disambiguation Latin was the language originally spoken in the region around Rome called Latium. It gained great importance as the formal language of the Roman Empire. All Romance languages are descended from Latin, and ma word for France, Gallia. He found the metal in a sample of zincZinc is a chemical element in the periodic table that has the symbol Zn and atomic number 30. Notable characteristics Zinc is a moderately reactive metal that will combine with oxygen and other non-metals, and will react with dilute acids to release hydro ore from the PyreneesFor other meanings see: Pyrenees, Victoria and Montes Pyrenaeus. The Pyrenees ( Spanish Pirineos French Pyrenees Catalan Pirineus Basque Aunamendi are a range of mountains in southwest Europe that form a natural border between France and Spain. They separ. A year later he isolated the element by electrolysisThis article is about the chemical process. Electrolysis is also a method of epilation. In chemistry and manufacturing, electrolysis is a method of separating bonded elements and compounds by passing an electric current through them. Overview The source m. It was later claimed that Lecoq had named the element after himself, since gallus is the Latin translation of the French le coq, but Lecoq denied this in an article of 1877. The existence of gallium had been predicted in 1871Events January January 18 The member-states of the North German Confederation unite into a single nation-state known as the German Empire. The King of Prussia is declared the first German Emperor as Wilhelm I of Germany. January 28 France surrenders to en by Mendeleyev, who called it eka-aluminium, and its discovery was a boost for Mendeleyev's theory of the Periodic Table. Later Lecoq discovered samariumPromethium Samarium Europium Sm Pu Full table General Name, Symbol, NumberSamarium, Sm, 62 Chemical series Lanthanides Group, Period, Block _, 6 , f Density, Hardness 7353 kg/m3, no data Appearance silvery white Atomic properties Atomic weight 150. 36(3) ( 1880) and dysprosium ( 1886).
Lecoq contributed further to the development of the periodic classification of elements by proposing, soon after its discovery, that argon was a member of new, previously unsuspected, group of elements, later to become known as the noble gases.
He died in Paris at the age of 74.
