In writing Lewis structures, what do double bond and triple bond between two atoms represent in terms of the number of electrons shared, should be explained. How to recognize when a molecule must contain double bond or triple bond should be explained. Resonance structures should be defined. Concept Introduction: In writing Lewis structures, a pair of shared electrons is represented by a bond. For convenience, a line is used to indicate each pair of bonding electrons. Sometimes we need to use double bond or triple bond to satisfy the octet rule. Finding the correct type of bond is a trial-and-error process. A molecule shows resonance when more than one Lewis structures are available for the molecule. Those various Lewis structures are called Resonance structures.
