Document Summary

Bond angle: the angle (in degrees) defined by lines joining the centers of two atoms to a third atom to which they are chemically bonded. Valence-shell electron-pair repulsion theory (vsepr): a model predicting the arrangement of valence electron pairs around a central atom that minimizes their mutual repulsion to produce the lowest energy orientations. Electron-group geometry: the three-dimensional arrangement of bonding pairs and lone pairs of electrons about a central atom. Molecular geometry: the three-dimensional arrangement of the atoms in a molecule. Steric number (sn): the sum of the number of atoms bonded to a central atom plus the number of lone pairs of electrons on the central atom. Linear: molecular geometry about a central atom with a steric number of 2 and no lone pairs of electrons. Trigonal planar: molecular geometry about a central atom with a steric number of 3 and no lone pair of electrons.
