aluminium
aluminium (symbol Al) Metallic silvery white element of group III of the periodic table. It is the most common metal in the Earth's crust; the chief ore is
bauxite from which the metal is extracted by electrolysis. Alloyed with other metals, it is used extensively in machined and moulded articles, particularly where lightness is important, such as aircraft. It is protected from oxidation (corrosion) by a thin, natural layer of oxide. Properties: at.no. 13; r.a.m. 26.98; r.d. 2.69; m.p. 660.2°C (1220.38°F); b.p. 1800°C (3272°F); most common isotope Al
27. Aluminium was first isolated in 1825 in an impure form by Danish physicist Hans Christian
Oersted. See also
