resonance


resonance
A situation that arises when two or more Lewis structures can be drawn to represent covalent bonding in an ion or moleculeA set of atoms joined by covalent bonds and having no net charge.. In each Lewis structure the atomic nuclei remain in the same positions; only the electrons move. When resonanceA situation that arises when two or more Lewis structures can be drawn to represent covalent bonding in an ion or molecule. In each Lewis structure the atomic nuclei remain in the same positions; only the electrons move. When resonance applies, bonding is considered to be an average superposition of the individual Lewis structures. applies, bonding is considered to be an average superposition of the individual Lewis structures.
