Valence shell electron pair repulsion theory is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms. It is also named the Gillespie-Nyholm theory after its two main developers, Ronald Gillespie and Ronald Nyholm.

lone pair electrons influence the shape of the molecular shape but don't impact the actual naming of the molecule. For example SO3_2- has resonance with a lone pair on the Sulfur. The shape is influenced by this lone pair but the name of the molecule shape is still trigonal pyramidal (not inclusive of the lone pair)
