Gallium does not exist as a free element in the Earth's crust, and the few high-content minerals, such as gallite (CuGaS2), are too rare to serve as a primary source. The abundance in the Earth's crust is approximately 16.9 ppm. This is comparable to the crustal abundances of lead, cobalt, and niobium. Yet unlike … See more Gallium is a chemical element with the symbol Ga and atomic number 31. Discovered by the French chemist Paul-Émile Lecoq de Boisbaudran in 1875, gallium is in group 13 of the periodic table and is similar to the … See more Gallium is found primarily in the +3 oxidation state. The +1 oxidation state is also found in some compounds, although it is less common … See more In 1871, the existence of gallium was first predicted by Russian chemist Dmitri Mendeleev, who named it "eka-aluminium" from its position in his periodic table. He also predicted several properties of eka-aluminium that correspond closely to the real properties of … See more Advances in trace element testing have allowed scientists to discover traces of dissolved gallium in the Atlantic and Pacific Oceans In recent years, dissolved gallium concentrations have presented in the Beaufort Sea. These reports reflect the possible profiles of … See more Elemental gallium is not found in nature, but it is easily obtained by smelting. Very pure gallium is a silvery blue metal that fractures See more Gallium is produced exclusively as a by-product during the processing of the ores of other metals.
