China Web23 aug. 2024 · Ionic crystals are constructed by a regular orientation of the oppositely charged ions which are considered as hard sphere. The ions are held together by the strong electrostatic forces. Within the crystal in addition to the coulombic forces there is a short range repulsive force originated from the interpenetration of the electronic clouds.
