Use the Lewis dot symbols to describe the formation of aluminium oxide (Al_2O_3) . Strategy: The Lewis dot symbols of Al and O are :Al*" "*ddotunderset(..)O* Thus, the common valency of Al is 3 while that of O is two. As a result, aluminium tends to form the trivalent cation (Al^(3+)) and oxygen, the divalent anion (O^(2-)) . The transfer of electrons is from Al to O. There are three valence electrons in each Al atom, each O atom needs two electrons to form the O^(2-) ion, which is isoelectronic, with neon. Thus, the simplest neutralizing ratio of Al^(3+) to O^(2-) is 2:3 , two Al^(3+) ions have a total charge of 6+ and three O^(2-) ions have a total charge of 6- . Thus, the empirical formula of aluminium oxide is Al_2O_3 .
