WebFeb 16, 2024 · The chemical symbol of germanium is 'Ge', with 32 as its atomic number in the periodic table. It is a hard and brittle element in nature. This element was discovered in 1886 by Clemens A. Winkler, a German chemist. He found it in an ore (presently called argyrodite) which was found near Freiberg, Germany by a miner. WebGallium was discovered in Paris by Paul-Émile Lecoq de Boisbaudran in 1875. He observed a new violet line in the atomic spectrum of some zinc he had extracted from a sample of zinc blende ore (ZnS) from the Pyrenees. He knew it meant that an unknown element was present. WebMar 27, 2024 · Germanium was first predicted by the Russian chemist Dmitri Mendeleev in 1869. He named it eka- silicon and predicted its properties based on its position in the periodic table. In 1886, Clemens Winkler, a German chemist, discovered germanium while analyzing a sample of the mineral argyrodite. crs ハイエース 大阪
