4 th edition, Hill, Petrucci, McCreary, Perry 10 VSEPR Notation and Strategy In the VSEPR notation used to describe molecular geometries, the central atom in a structure is denoted as A , terminal atoms as X , and the lone pairs of electrons as E . Applying the VSEPR method: 1. Draw a Lewis structure of the molecule or ion; 2. Determine the number of electron groups; 3. Identify the electron-group geometry; 4. Identify the molecular geometry.
