VSEPR

Front

What is VSEPR theory?

Back

VSEPR (Valence Shell Electron Pair Repulsion) theory is a model used to predict the geometry of individual molecules based on the repulsion between the electron pairs in the valence shell of the central atom.

What does VSEPR stand for?

Back

VSEPR stands for Valence Shell Electron Pair Repulsion.

Front

What is the basic principle of VSEPR theory?

Back

The basic principle of VSEPR theory is that electron pairs around a central atom will arrange themselves as far apart as possible to minimize repulsion.
