A VSEPR Chart (or "VSEPR Model") is a handy tool to use both in the classroom and when studying at home. The chart is widely known for helping students in understanding molecular geometry and is generally used during freshman-level Chemistry lessons. VSEPR is short for "Valence Shell Electron Pair Repulsion," a chemical theory originally developed by R. Gillespie and R. Nyholm for forecasting the shapes of molecules based on the amount of electron pairs circling a central atom. A VSEPR Chart PDF version can be downloaded through the link below.
Knowing the geometry of molecules is vital to understanding its reactions. VESPR provides a simple method of predicting the geometries of main group compounds. The theory is applied when predicting the combinations of electron doubles around atoms in simple and symmetric molecules. In them, central atoms attach to two or more other atoms. The shapes of these key atoms and the non-bonding electron doubles influence the shape of the larger whole.
