VSEPR: Valence Shell Electron Pair Repulsion Theory

Valence Shell Electron Pair Repulsion Theory, or VSEPR for short, is a model used to predcit the geometry of molecules. A key factor in VSEPR is consider the number of electron pairs in the valence shell around a central atom in a molecule. Use the applet below to learn the basics of this theory.

The full version of the VSEPR program has over 50 molecules and has no time limitation.
