Concept explainers
Interpretation:
The trend of decreasing lattice energies of the chlorides of the Group 2 metals compound has to be explained.
Concept Introduction:
A three-dimensional array of ions constitutes the ionic compound lattice. They are stabilized because of attractive forces oppositely charged ions that lower the potential energy. The lattice energy of strong ionic solids is often very large because of small and densely charged ions.
Lower is the potential energy of interaction and more stable is the ionic solid. Hence the compounds that have high charge density on small space are the most stable ionic solids. For example, the calcium phosphate is made up of
