VSEPR Theory
... brought to you by Dr. McCord

the FIVE core electronic geometries

These are the 5 core geometries that all VSEPR theory is based on. There are another 6 geometries that are subsets of these five. The subsets are made by substituting electron lone pairs into the positions instead of atoms.

Click on any of the geometry names to open a page about that geometry and all its subsets.
