What Does VSEPR Stand For?

VSEPR stands for Valence Shell Electron Pair Repulsion

VSEPR, or Valence Shell Electron Pair Repulsion, is a theoretical model used in chemistry to predict the three-dimensional geometries of molecules. The principle behind VSEPR is that electron pairs in the valence shell of an atom will arrange themselves to minimize repulsion between them, leading to distinct molecular shapes. This model helps to explain and predict the bond angles and overall molecular structure based on the number of bonding and non-bonding electron pairs surrounding a central atom.
