Starting with magnesium and oxygen atoms, use Lewis diagrams to show the formation of the ionic compound Mgo.

The electronic configuration of the magnesium atom shows that it has two unpaired outermost shell electrons while that of oxygen shows that it has six outermost shell electrons with two of them unpaired.

By means of elecron transfer, magnesium atom donates its two electrons to the oxygen atom to now have a charge of +2 while the oxygen then has a charge of -2. This results in an ionic bonding between the two atoms.

Explanation:

The structure is found in the attachment below

answer: i dont know the answer but this might

explanation:

l

it is stable as it is in group 0 which have full outer shells of electrons
