Resonance (chemistry) - Wikipedia, the free encyclopedia
Resonance in chemistry is a key component of valence bond theory used to graphically represent and mathematically model certain types of molecular structures when no single, conventional Lewis struct...

Equivalent Lewis structures are called resonance structures, or resonance forms ... This indicates that the ozone molecule is described by an average of the two Lewis structures (i.e. the resonance forms) ... Are there possible resonance structures? YES...

Additional reading recommendation: You may find Chapter 2 of Pushing Electrons by Daniel P. Weeks (Saunders College Publishing; ISBN 0-03-0206936) to be a useful tool for mastering the fundamentals of resonance structures.

Three equivalent Lewis structures (formal charges are included) can be drawn for the carbonate ion. The true structure of the carbonate ion is an average of the three resonance structures connected by a double headed arrow and enclosed in brackets.

A resonance structure is an alternate way of drawing a Lewis dot structure for a compound. For some molecules, there are multiple ways to draw a Lewis dot structure that still satisfy the rules (for instance, having the correct total electr...

Lewis structures that differ only in the position of the electrons are called resonance structures. The actual structure of the species is a blend of the resonance structures and more stable than any one of them.

Though the structures may appear to be different, they are actually resonance structures of the same molecule. Experimental measurements show that neither structure is exactly correct, but that the molecule found in nature is a combination of structures called a resonance structure...

Collectively these Lewis diagrams are then known as resonance structures or resonance contributors or resonance canonicals. The "real" structure has characteristics of each of the contributors, and is often represented as the resonance hybrid (think of a hybrid breed which is a mixed breed).
