The VSEPR model can predict the structure of nearly any molecule or polyatomic ion in which the central atom is a nonmetal, as well as the structures of many molecules and polyatomic ions with a central metal atom.
29 Σεπ 2022 · VSEPR is the acronym for Valence Shell Electron Pair Repulsion theory. VESPR is a model used to predict the geometry of molecules based on minimizing the electrostatic repulsion of a molecule's valence electrons around a central atom. Pronunciation: vesper.

VSEPR theory is used to predict the arrangement of electron pairs around central atoms in molecules, especially simple and symmetric molecules. A central atom is defined in this theory as an atom which is bonded to two or more other atoms, while a terminal atom is bonded to only one other atom.
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.
21 Σεπ 2022 · The acronym VSEPR stands for the valence-shell electron pair repulsion model. The model states that electron pairs will repel each other such that the shape of the molecule will adjust, so that the valence electron-pairs stay as far apart from one another as possible.
Definition. VSEPR (Valence Shell Electron Pair Repulsion) Theory is a model used to predict the three-dimensional shapes of molecules based on the repulsion between electron pairs in the valence shell of atoms.
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.
