About Shape of Ionic Crystals
Ionic crystal shape depends on the regular arrangement of oppositely charged ions in a three-dimensional lattice. The topic covers coordination number, radius ratios, lattice geometry and structures such as sodium chloride, caesium chloride and zinc sulfide, which should not be confused with the molecular shapes predicted by VSEPR theory.
