3. Properties of Molecules
Covalent bonding
    Lewis structures of molecules and ions.

Electronegativity and Polar Molecules
    Electronegativity in relation to periodic table; polar and non-polar molecules.

Molecular Shape and Structure
    Geometric arrangements of groups in atoms; VSEPR theory.

Applying VSEPR Theory
    VSEPR theory applied to molecules with non-bonding pairs and multiple bonds.

Valence Bond Model of Covalent Bonding
    Atomic orbitals revised; valence bond model applied to some diatomic and triatomic molecules.
