Lewis Structure and Properties of AlCl6 3-

The video tutorial explains how to write the Lewis structure for AlCl6 3-. It begins by counting the valence electrons, considering aluminum and chlorine's group numbers, and accounting for the 3- charge. The total is 48 electrons. Aluminum is placed at the center of the structure, surrounded by chlorine atoms. Pairs of electrons form bonds between aluminum and chlorine, and the octet rule is applied to chlorine. Aluminum can exceed the octet rule. The structure is enclosed in brackets with a 3- charge. The molecular geometry is determined to be octahedral due to six bonded atoms and no lone pairs.
