We’re being asked to determine the formal charge of all O atoms in O3. To do so, we need to do the following steps:
Step 1: Determine the central atom in this molecule.
Step 2: Calculate the total number of valence electrons present.
Step 3: Draw the Lewis structure for the molecule.
Step 4: Calculate the formal charge for the indicated atom. Recall that the formula for formal charge is:
What are the formal charges in O3 (ozone)?
