a.Introduction to Chemical Bonding presents the basics of chemical bonding including valence electrons, Lewis dot structures, electronegativity, ionic, covalent, and polar covalent bonding.

b.Polar Covalence presents the details of polar covalent bonds including properties associated with bond types, polar molecule behavior in electric fields, predicting degree of polarity, orbital overlap with regard to bond formation and strength, and prediction of properties due to bond polarity.

c.Bond Type and Properties of Matter describes bonding in terms of electrostatic attraction and repulsion, and correlates properties of substances with the bonding and structure of elements and compounds.

2. CHEM Study Films and Videos (1/2 -inch VHS) All the original CHEM Study films have been revised and brought up to date. They are also available in convenient video format. Highly recommended-particularly the first and third titles listed below.Crystals and their Structures also fits well in a Condensed States unit. Available from Ward's Natural Science Establishment, P.O. Box 92912, Rochester, NY 14692-9012, (800) 962-2660, in VHS format or 16-mm film format for purchase or rental.

a.Chemical Bonding explains chemical bonding in terms of the electric interactions that cause bonding in the hydrogen molecule. 16 min. Recommended for average or better students.

b.Crystals and their Structures introduces the properties of crystals, their well-defined diffraction patterns in interaction with X-rays, and their description as regular, repeating arrangements of atoms. 22 min. Recommended for above average students.

c.Electric Interactions in Chemistry develops Coulomb's law experimentally in a way that average or better students can grasp. The experiment used is somewhat unique. 21 min. Recommended for average or better students.

d.Shapes and Polarities of Molecules develops the concept of molecular polarity. Polar molecules are used to explain differences in solubility, electrical conductivity, and chemical reactivity. 18 min. Recommended for average and above average students.
