WebΔ Hlattice = C ( Z + ) ( Z− )/ Ro. in which C is a constant that depends on the type of crystal structure; Z+ and Z– are the charges on the ions, and Ro is the interionic distance (the sum of the radii of the positive and negative ions). Thus, the lattice energy of an ionic crystal increases rapidly as the charges of the ions increase and ... WebAn Ionic compound always contains an equal amount of positive and negative charge. For example: In calcium chloride, the ionic bond is formed by oppositely charged calcium and chloride ions. The calcium atom loses 2 electrons and attains the electronic configuration of the nearest noble gas (Ar). By doing so, it gains a net charge of +2.
