VSEPR

VSEPR, or Valence Shell Electron Pair Repulsion, is a model used in chemistry to predict the shape of molecules. Developed by American chemist Donald Cowley, VSEPR theory explains how the electron pairs around an atom affect the arrangement of its bonded pairs and lone pairs.

According to VSEPR, electron pairs around an atom repel each other due to their negative charge. The

The VSEPR model categorizes electron pairs as either bonded pairs or lone pairs. Bonded pairs are the

The main goal of VSEPR is to predict the molecular shape based on the number and arrangement

The VSEPR model is a fundamental concept in modern chemistry and is used extensively in fields ranging
