Answer:

D

Explanation:

In ionic bonding, attraction occurs between two atoms based on the differences in their electronegativities.

The formation of an ionic bond involves a transfer of electrons from the less electronegative atom usually the metal to the more electronegative atom(non-metal) such that the two kinds of atoms now have a completely filled outer shell like the noble gases.

The transfer of electrons causes the non-metal to be negatively charged and the metal to be positively charged:

   Mg     →  Mg²⁺ + 2e⁻

 2,8,2        2,8

    O +  2e⁻   →  O²⁻

    2,6                2,8

Option D shows the valence electrons using the electron dot formula. The ionic bond is perfectly shown by the diagrammatic representation in D.
