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⁻

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
