Question

give the electron lot of Na, o and mg​

Answer 1

Explanation:

Sodium .2.8.1

Oxygen .2.6

Megnesium.2.8.2

Thus 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.

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.
