Final answer:
Ozone (O3) has more than one resonance structure to accurately depict its electron configuration, with a total of 18 valence electrons forming a bent molecular shape without an overall charge. A central carbon atom does not feature in its structure.
Step-by-step explanation:
The Lewis structures for ozone (O3) indicate that the molecule exhibits resonance, which means that more than one Lewis structure is needed to represent the bonding in the molecule accurately. In the case of ozone, two equivalent resonance structures can be drawn, showing the electrons in different positions but with the atoms remaining in the same arrangement.
The ozone molecule has a total of 18 valence electrons, which are used to form bonds and lone pairs. The ozone molecule does not contain carbon, unlike the provided structure indicating a central carbon atom, so this part is incorrect. When drawing the Lewis structure for ozone, each oxygen atom is connected to one another, with one double bond and one single bond between the oxygen atoms, and the double bond shifts between the oxygen atoms in the different resonance forms. Ozone has a bent molecular shape and the molecule itself does not have an overall charge.
