Hardness of Solid Substances - Grinding A number of metals and nonmetals are ground with a mortar and pestle. The nonmetals shown here are all soft (due to weak intermolecular forces), but the metals vary in hardness.

Bonding : MatchBondStrength (8 Variations)
Match each of the following molecules to the best energy value for each bond. Do not use the table of bond energies in your book, but predict these values using your knowledge of bond length and bond strength.
Possible energies are: 300 kJ/mol, 330 kJ/mol, 415 kJ/mol and 950 kJ/mol.
Valence, Covalence, Hypervalence, Oxidation State, and Coordination NumberDerek W. Smith It is argued that the terms valence, covalence, hypervalence, oxidation state, and coordination number are often confused and misused in the literature. It is recommended that use of the term valence, and its associated terminology, should be restricted to simple molecular main group substances and to some oxoacids and derivatives, but avoided in both main group and transition element coordination chemistry. Smith, Derek W. J. Chem. Educ.2005, 82, 1202.

Electronegativity and the Bond TriangleTerry L. Meek and Leah D. Garner The dependence of bond type on two parameters, electronegativity difference (??) and average electronegativity (?av), is examined. It is demonstrated that ionic character is governed by the partial charges of the bonded atoms, and metallic character by the HOMOLUMO band gap. Meek, Terry L.; Garner, Leah D. J. Chem. Educ.2005, 82, 325.

Teaching Molecular Geometry with the VSEPR ModelRonald 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.
