A molecule or ion with such delocalized electrons is represented by several resonance structures. In physics, resonance is a phenomenon in which a vibrating system or external force drives another system to oscillate with greater amplitude at specific frequencies. A familiar example is a playground swing, which acts as a pendulum. Sometimes one Lewis.
In chemistry, resonance is a way of describing bonding in certain molecules or ions by the combination of several contributing structures (or forms, also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory. Jul Theory of resonance, in chemistry, theory by which the actual normal state of a molecule is represented not by a single valence-bond structure.
Resonance_(chemistry)en. Introduction to resonance structures, when they are use and how they are drawn. Electrons in σ bonds have a fixed location and so they are said to be localised.
