The incorrect statement regarding the formation of ionic bond

- Ionic bond involves the electrostatic attraction between oppositely charged ions or between two atoms with sharply differing electronegativities.
 Negatively charged ions are formed when atoms gain electrons (called anions). Ions are positively charged atoms that have lost their electrons (called cations).
- The formation of the ionic bond is exothermic.
- Ionic bonding can occur as a result of a redox reaction in which atoms of a low-ionization-energy element (typically metal) give up part of their electrons to achieve a stable electron configuration.
