The valence shell electron pair repulsion model is often abbreviated as VSEPR (pronounced "vesper") and is a model to predict the geometry of molecules. Specifically, VSEPR models look at the bonding and molecular geometry of organic molecules and polyatomic ions.
The valence shell electron pair repulsion theory or VSEPR theory is used to predict the three-dimensional shape of a molecule. According to this theory, the molecular shape depends on the repulsion between the valence shell electron pairs of the central atom.
The valence shell electron pair repulsion theory (VSEPR) predicts the shape and bond angles of molecules. Electrons are negatively charged and will repel other electrons when close to each other. In a molecule, the bonding pairs of electrons will repel other electrons around the central atom forcing the molecule to adopt a shape in which these ...
Valence shell electron-pair repulsion theory (VSEPR theory) enables us to predict the molecular structure, including approximate bond angles around a central atom, of a molecule from an examination of the number of bonds and lone electron pairs in its Lewis structure.
VSEPR theory is where electrons in the valence shell of an atom repel each other, they can affect the geometry of a bonds in a molecule. Molecule geometry describes the location and angles between bonds in regards to the location of electron density (where electrons are located).
Lecture Video. Valence shell electron pair repulsion or VSEPR theory can be used to predict molecular geometry. The theory is based on Lewis structures and the simple idea that that the preferred geometry around a central atom is the one that minimizes electron repulsion.
