# A Lewis electron-dot diagram representing one resonance contributor of an ozone molecule, \(\text{O}_3\), is shown above. When both equivalent resonance contributors to the resonance hybrid are taken into account, what is the average formal charge on each terminal oxygen atom?

A Lewis electron-dot diagram representing one resonance contributor of an ozone molecule, \(\text{O}_3\), is shown above. When both equivalent resonance contributors to the resonance hybrid are taken into account, what is the average formal charge on each terminal oxygen atom?

![A Lewis electron-dot structure of an ozone molecule, \(\text{O}_3\), consisting of three oxygen atoms arranged horizontally. The central oxygen atom is bonded to the left oxygen atom by a double bond represented by two horizontal parallel lines, and bonded to the right oxygen atom by a single bond represented by one horizontal line. The left oxygen atom has exactly two lone pairs shown as four solid black dots (one pair directly above the atom and one pair to its left; no dots below or to the right). The central oxygen atom has exactly one lone pair shown as two solid black dots directly above the atom (no dots below). The right oxygen atom has exactly three lone pairs shown as six solid black dots (one pair above, one pair to its right, and one pair below; no dots to the left). All atoms and bonds are rendered in grayscale. No other atoms, lone pairs, bonds, formal charges, partial charges, brackets, or annotations appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1787299919-Mw6CCO.jpg)
