Structure
Ozone can be assigned two different Lewis structures, but neither one accurately represents the structure and bonding in the O3 molecule.

Spectroscopic data indicates both O−O bonds in ozone are equal in length and strength. The central oxygen atom is positively charged and the terminal oxygen atoms each carry partial negative charge.
