What is the formal charge on the central oxygen atom in the ozone () molecule? — Chemical Bonding Chemistry Question

💡 Solution & Explanation

In $O_3$, the central O atom has 6 valence electrons, 1 lone pair (2 non-bonding electrons), and 3 bonds (6 bonding electrons). Formal Charge $= 6 - 2 - \frac{1}{2}(6) = +1$.
