- 6.3: Resonance - Equivalent Lewis Structures for The Same Molecule
- Resonance is the use of two or more Lewis structures to represent the covalent bonding in a molecule. One of the valid structures is referred to as a resonance structure. It is now understood that the true structure of a molecule which displays resonance is that of an average or a hybrid of all the resonance structures.

- 6.4: Molecular Geometry
- Molecules have shapes. There is an abundance of experimental evidence to that effect—from their physical properties to their chemical reactivity. Small molecules—molecules with a single central atom—have shapes that can be easily predicted. The basic idea in molecular shapes is called valence shell electron pair repulsion (VSEPR).

- 6.6: Content in Context
- In this unit, we'll explore how chemistry helps us understand the composition of the air around us and the effects of pollutants on our health and environment. Now that you've learned to name chemical compounds, we'll apply that knowledge by identifying common air pollutants ...
