Explanation:

The Lewis structure of a substance is otherwise known as its dot electron structure. It gives an immediate picture of the bonding and number of electron pairs in the molecule. The diagram shows only the valence electrons on each of the bonding atoms in the molecule and how they combine to form the molecule under consideration.

The correct Lewis structure for CO2  is shown in the image attached. CO2 has 16 valence electrons. This can be verified by counting the number of dots in the image attached.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
