Exploring Solid-State Structure and Physical Properties: A Molecular and Crystal Model Exercise Thomas H. Bindel This laboratory allows students to examine relationships among the microscopicmacroscopicsymbolic levels using crystalline mineral samples and corresponding crystal models. The exercise also reinforces Lewis dot structures, VSEPR theory, and the identification of molecular and coordination geometries. Bindel, Thomas H. J. Chem. Educ. 2008, 85, 822.

Teaching Molecular Geometry with the VSEPR Model Ronald J. Gillespie The difficulties associated with the usual treatment of the VB and MO theories in connection with molecular geometry in beginning courses are discussed. It is recommended that the VB and MO theories should be presented only after the VSEPR model either in the general chemistry course or in a following course, particularly in the case of the MO theory, which is not really necessary for the first-year course. Gillespie, Ronald J. J. Chem. Educ. 2004, 81, 298.

Simplified Lewis Structure Drawing for Nonscience Majors Barnabe B. Miburo Lewis structures are drawn using a simplified novel method with the following features: 1) the atoms used are brought in carrying all their valence electrons; 2) bonds are created by pairing up valence electrons between the central atoms and peripheric atoms; 3) anions are formed by addition of electrons to single electrons on appropriate atoms, while cations are formed by removal of single electrons. Miburo, Barnabe B. J. Chem. Educ. 1998, 75, 317.

Lone pair electrons Fowles, Gerald W. A. The lone pair electrons, whether in simple or hybrid orbitals, have profound effects on the properties of the molecule; these effects may be discussed as bond angles, dipole moments, bond energies and lengths, and coordination and hydrogen bonding.
