Correct answer: option 4 that is to say, transferred from the valence shell of the atom atom to the valence shell of another atom. Reason: Ionic bonds are preferentially formed when there is large difference in electronegativity of bonding atoms. The atom that is highy electronegative in nature tend to accept electrons from an element electropositive. The stability of these two atoms increases because, during the process of exchange of electrons and acquires the electron configuration of the inert gas nearest to you. For example: In NaCl, Na donates a proton to Cl. In ionised form, Na acquires the electron configuration of 1s2 2s2 2p6, while the electronic configuration of the Cl it becomes 1s2 2s2 2p6 3s2 3p6. Therefore, in the present case, the electrons are transferred from the valence shell of Na valence shell of Cl
