VSEPR Table

The VSEPR Table is a handy piece of software that can help users prepare for their next presentations or study for their Chemistry exams by providing them with various useful bits of data that are neatly organized within the main screen. The information can be easily accessed even by inexperienced users.

VSEPR stands for Valence Shell Electron Pair Repulsion and is a model that is used in chemistry to predict the geometry of various individual molecules by using the number of electron pairs that surround their central atoms.

The principle enunciates that the pairs of electrons that surround an atom try to repel each other and will arrange themselves in such a manner that will minimize this interaction.

This VSEPR Table includes molecular geometries, their names and angles so that molecular shape can be predicted from the 2D Lewis structure based on the number of bonding electron pairs and the number of lone electron pairs.

Unlike other theories, this one is based not on mathematical wave functions, but on observable electron density. Its applicability includes a few QCT (quantum chemical topology) methods. Some of them are the QTAIM (quantum theory of atoms in molecules) or the electron localization function.
