2. WARNING: As with everything you learn in chemistry class, or anywhere in school, the following is a gross oversimplification of reality.

3. SWBAT . . .

4. * help chemists predict the behavior of elements.
Lewis Structures
* help chemists predict the behavior of elements.
* are based on the electron configurations of the elements.
* are determined by elements’ positions on the periodic table.
* are more easily understood if you first know how the periodic table is arranged.
