Ionic Bonds Having Covalent Character

[Sabah Islam 1G]

Can someone clarify why ionic bonds display covalent character and how high polarization relates to this?

[An Dang 3F]

Ionic bonds can have covalent character because the cation's positive charge will attract the anion's electron, so the anion's electron cloud will be distorted towards the cation. This electron cloud distortion can be considered as a bond that acts like a covalent bond. Ionic bonds will have more covalent properties when the distortion of the electron cloud increases when the anion has a large radius or when the cation is highly charged.

[James Nguyen 3G]

All Ionic bonds have covalent character because there is still attraction between the cation and the electrons that the anion contains, which causes a 'distortion' of the electrons, which is similar to a covalent bond and creates covalent character depending on the level of distortion.
