VESPR (Valence Shell Electron Pair Repulsion) is used to determine the shape of the molecules based on their number of electron pairs and how they interact with each other via repulsion. Different numver of electron pairs will form different shapes, e.g. 0 pairs = linear, 1 = pyramidal...
its used to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms.
