Explain the covalent character in ionic bond.

Explanation

The partial covalent character in ionic compounds can be explained on the basis a polarisation . In an ionic compound, there is an electrostatic attractive force between the cation and anion . The positively charged cation attracts the valence electrons of anion while repelling the nucleus . This causes a distortion in the electron cloud of the anion and its electron density drifts towards the cation, which results in some sharing of the valence electrons between these these ions. us, a partial covalent character is developed between them. This phenomenon is called polarisation .
