Concept Introduction:
In any polar covalent bond, the difference in electronegativities gives rise to partial positive and negative charges respectively on the cation and anions.
The covalent character is determined with respect to the relative extent of distortion of the anionic cloud of the anion. For instance, highly charged small alkali metal cation such as
The covalent or ionic character of a polar covalent bond is determined on the basis of difference in electronegativities. If the difference exceeds 2, the compound is regarded as predominantly ionic. If it is much than 2 it is regarded as covalent in nature.
