The Valence Shell Electron Pair Repulsion Model Balloons tied together adopt arrangements which minimize steric clashes between neighbors: Atoms are bonded together by electron pairs in valence orbitals Electrons are all negatively charged and tend to repel other electrons Bonding pairs of shared electrons tend to repel other bonding pairs of electrons in the valence orbital The best spatial arrangement of the bonding pairs of electrons in the valence orbitals is one in which the repulsions are minimized

Unformatted text preview: Like the balloon example: • Two electron pairs in the valence orbital are arranged linearly • Three electron pairs are organized in a trigonal planar arrangement • Four electron pairs are organized in a tetrahedral arrangement • Five electron pairs are arranged in a trigonal bipyramid • Six electron pairs are organized in an octahedral arrangement The shape of a molecule can be related to these five basic arrangements...
