Does a giant ionic structure (compound) always comprise of equal quantites of each atom/ion it is formed of? Is it correct that cations and an anions bond to form a compound of no charge? I say this becuase I saw a diagram of an ionic structure in a book that had one more cation than anions (this has confused me). If a structure were to be like this would it not have a positive charge (rather than no charge)? For a giant ionic structure to have its characteristic 'no charge' would it not need to comprise of equal quantities of each type of ion?
