Vedclass · Answer

(D) The formal charge on an atom in a Lewis structure is calculated using the formula:Formal Charge = (Total number of valence electrons on the free atom) - ($\frac{1}{2}$ $	imes$ Total number of shared electrons) - (Total number of unshared valence electrons).For the central oxygen atom in the ozone $(O_3)$ molecule:$1$. The central oxygen atom has $6$ valence electrons in its free state.$2$. It forms one double bond with one oxygen atom and one single bond with another oxygen atom,sharing a total of $6$ electrons ($3$ bonds $	imes$ $2$ electrons per bond).$3$. It has $2$ unshared electrons (one lone pair).Formal Charge = $6 - \frac{1}{2}(6) - 2 = 6 - 3 - 2 = +1$.

The formal charge on the central oxygen atom in ozone $(O_3)$ is:
