Unformatted text preview: charge pulls the 2s electrons closer, which decreases the 2s and 2p electronic interactions causing 2p to drop below 2p Resonance: sharing of electrons between properly oriented orbitals Real molecules are hybrids or an average of these limiting structures Resonance structures are only if the electrons move; if nuclei have moved, it is not a resonance structure...
