Oxygen Dot Diagram. Lewis structure of co2 the central atom of this molecule is carbon. There are now four unpaired electrons around the oxygen symbol.
Then place one dot at each side of the symbol. I the electronic configuration of oxygen is 26. The molecule has one oo double covalent bond displayed formula oxygen valency 2.
How can one draw a lewis structure and use it to understand how atoms bond together to make molecules.
First draw single bonds between the atoms. Oxygen is in group 16via so it has six valence electrons. Then place one dot at each side of the symbol. The electrostatic attraction between the oppositely charged ions forms the ionic bond between lithium and oxygen.
