Valence Electrons in Ozone Molecule

The video tutorial explains the process of drawing the Lewis structure for ozone, which involves distributing 18 valence electrons among three oxygen atoms. Initially, electrons are placed to form single bonds and complete the octets of the outer oxygens. The central oxygen ends up with only six electrons, so a double bond is formed by sharing electrons, ensuring all oxygens have full octets. The tutorial concludes with a review of the completed structure.
