According to the model, the electron domains (bonding and nonbonding pairs of valence electrons) located around the central atom of the molecule repel each other, causing them to rearrange so that repulsive forces are minimized. The electron geometry of a molecule describes the arrangement of electron domains whereas the molecular geometry describes the arrangement of bonded atoms. The molecular geometry depends on the number of bonding versus nonbonding (lone pair) electron domains. Lone pairs exert more repulsion than bonding electrons, resulting in a compression of bond angles relative to the electron geometry. As such, if two molecules have the same number of electron domains but differ in the number of lone pairs, they will have different molecular geometries. An octahedral molecular geometry results from six bonding domains and no lone pairs symmetrically arranged around a central atom. The Lewis structures for SeCl₆ and SF₃Cl₃ consist of six electron domains (six single bonds) located on the central atoms, Se and S, respectively, and are octahedral (Numbers II and III). (Number I) When evaluating the molecular geometry, lone pair electrons are "invisible" but do exert a force. Although ClF₅ contains six electron groups (five single bonds and one lone pair), the increased repulsion from the lone pair pushes the five bonding domains closer together to form a square pyramidal molecular geometry. (Number IV) CF₄ is tetrahedral with four electron domains (four single bonds) symmetrically arranged around the central C atom. Educational objective: The valence-shell electron-pair repulsion (VSEPR) model can be used to predict molecular geometry. An octahedral geometry forms when six bonding electron domains are arranged symmetrically around the central atom of a molecule.
