The lewis dot notation for two atoms is shown. mg is written with two dots on its right. o is written on the right of mg. there are six dots around o. two arrows point from the dots near mg to o. what is represented by this notation?

mg gains two protons from o.

mg donates two protons to o.

mg gains two electrons from o.

mg donates two electrons to o.

Mg donates two electrons to O.

Explanation:

In Lewis dot notation Mg is written with two dots on its right.

O is written on the right of Mg.

There are six dots around oxygen.

Two arrows points from the dots near Mg to O.

This notation shows that two electron of magnesium is donates to oxygen.

Magnesium is present in group two. it has two valance electrons.

Oxygen is present in group 16. It require to electron to complete the octet.

Magnesium atom loses its two electrons which is accepted by oxygen.

Magnesium is form cation Mg²⁺ and oxygen form anion O²⁻
