WARNING: As with everything you learn in chemistry class, or anywhere in school, the following is a gross oversimplification of reality.
SWBAT . . . . . . draw Lewis structures. Rn
* 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.
