Double Bonds: In Lewis Theory, Atoms Can Share More Than One Electron Pair to Attain an Octet

• We know from Chapter 5 that oxygen exists as the diatomic molecule.
• If we pair two oxygen atoms together and then try to write a Lewis structure, we do not have enough electrons to give each O atom an octet.
• We can convert a lone pair into an additional bonding pair by moving it into the bonding region.
