Valence shell electron pair repulsion (VSEPR) theory is a model used to predict the geometry of individual molecules based on the repulsion between electron pairs around a central atom. The theory posits that electron pairs will arrange themselves to minimize repulsion, resulting in specific molecular shapes such as linear, trigonal planar, tetrahedral, and others.

VSEPR theory, or Valence Shell Electron Pair Repulsion theory, is used to predict the geometry of molecules based on the repulsion between electron pairs in the valence shell of the central atom. It helps determine the three-dimensional shape of a molecule by minimizing the repulsion between electron pairs, whether they are bonding or non-bonding.

The central atom in a molecule is the atom to which other atoms are bonded, often determining the molecule's geometry and properties. It is usually the atom with the highest bonding capacity or the least electronegative element in the compound.
