These structures will look like...

These structures are called resonance forms. A resonance form does not represent what the true structure actually looks like. It is merely one of the electron-dot formulas that is possible for the compound. In ozone, both of the oxygen-oxygen bonds have double bond and single bond character. The negative charge is spread equally between both of the outer oxygen atoms. We can write a mechanism for this phenomenon showing how 2 of the electrons jump back and forth.

This movement of electrons is constantly happening and we think of the real structure as an average of the 2 equal resonance forms.
