... 1. Charge density. This is the ratio of an ion’s charge to its size. Na+ ions are large with a small charge, so have a low charge density. Al3+ ions are smaller with a larger charge, and so have a higher charge density. They are therefore more strongly attracted to the delocalized electrons. 2. Numb ...
