VSEPR Model and Molecular Geometry Basic Concept. VSEPR Theory- The valence-shell electronic-pair repulsion (VSEPR) model is an approach of using the number of electrons surrounding a central atom to study the molecular structures, based on the theory that the structure around a given atom is determined principally by minimizing electron-pair repulsions.

Ozone. In this example, O 3, the Lewis diagram shows O at the center with one lone electron pair and two other oxygen atoms attached.This shows trigonal planar for the electron pair geometry and and bent the molecular geometry. The one lone electron pair exerts a little extra repulsion on the two bonding oxygen atoms to create a slight compression to a 116 o bond angle from the ideal of 120 o.

NO2- has one more electron than NO2, so it has a non-bonding pair ("lone pair") of electrons on nitrogen. This exerts a greater repulsion than the single electron in NO2, so the O-N-O angle is reduced further, to 115.4°. Nitrite ion with an O-N-O bond angle of 115.4° (according to Gillespie and Hargittai).
