Aluminium Group

A rare element occurring in the emerald and beryl. The metal resembles aluminium and its compounds resemble those of Al, [Pg.158]

Si/ nbol = A1—Atomic weight = 27—Molecular weight = 55 ( )— j5fp. gr. = 2.56-2.67—Fuses at about 700° (1292° F.)—Name from alumen=o litm—Discovered by Wohler, 1827. [Pg.159]

Preparation.—(1.) By decomposing vapor of aluminium chlorid by Na or KCWOhler). (2.) Aluminium hydroxid, mixed with sodium chlorid and charcoal, is heated in Cl, by which a double chlorid of Na and A1 (2NaCI, AhCh) is formed. This is then heated with Na, when A1 and NaCl are produced. (The industrial process.) [Pg.159]

Properties.—Physical.—A bluish-white metal hard quite malleable, and ductile, when annealed from time to time slightly magnetic a good conductor of electricity non-volatile very light, and exceedingly sonorous. [Pg.159]

Chemical.—It is not affected by air or O, except at very high temperatures, and then only superficially. If, however, it contain Si, it burns readily in air, forming aluminium silicate. It does not decompose HaO at a red heat but in contact with Cu, Pt, or I, it does so at 100° (212° F.). It combines directly with B, Si, 01, Br, and I. It is attacked by HCl, gaseous or in solution, with evolution of H, and formation of AlaCl . It dissolves in alkaline solutions, with formation of aluminates, and liberation of H. It alloys with Cu to form a golden yellow metal (aluminium bronze). [Pg.159]

The electrical conductivity increases across the metals of Period 3 from sodium (Group 1) to aluminium (Group 13). The electrical conductivity then drops dramatically to silicon, which is described as a semiconductor, and falls even further to the non-metallic insulators phosphorus and sulfur. [Pg.161]
