Resonance structures: when a single Lewis structure does not adequately represent a substance, the true structure is intermediate between two or more structures which are called resonance structures and these structures are created by moving electrons, not atoms.
Bond length is the distance between the nuclei in a bond and it is related to the sum of the covalent radii at the bonded atoms.
Bond length is inversely proportional to the bond order.
