We are being asked to identify the resonance forms of ozone (O3)
We will have to draw the Lewis Structure of O3 first.
Step 1: Determine the central atom in this molecule.
• 3 O atoms are the central atoms
Step 2: Calculate the total number of valence electrons present.
Group Valence Electrons
O 6A 6 valence e‑ x 3
Total = 18 valence e-
Step 3: Draw the Lewis Structure for the molecule
• O → prefers to have a complete octet (8 e- around them)
Write the resonance forms of ozone, O 3, the component of the upper atmosphere that protects the Earth from ultraviolet radiation.
