| Abstract: | The Born model is used as a method to assess the ionicity and the extent of covalent contribution to the binding in lead chloride. In the process, the Madelung constant (11·2429 with respect to cube root of unit cell volume) and cohesive energy (W L) (484 kcal/mole) are evaluated. The theoreticalW L, when compared with that derived from a thermochemical cycle indicates that PbCl2 can be considered to be ‘predominantly ionic’. |
