Explanation:

When the valence electrons are represented as dots circling the elements it is known as the elemental structure with electron -dot.

Thus for option i) we can write Sodium (2, 8, 1) = Na with one electron at the top. Again for Oxygen (2, 6) = O with two electrons each on three sides.

For Magnesium (2, 8, 2) = Mg with two electrons on the top. =

The formation of Na20 and MGO can be written as Mg2+ + 02 (2-).

In Na20, Na+ and O2- ions are present and in MgO, Mg2= and 02 (2-) ions are present.
