The three major kinds of bonding (ionic, covalent, and metallic) were discussed, including rules for identifying such bonds.
Polar and nonpolar covalent bonds were introduced and the guidline "Like dissolves like." was explained.
Polyatomic Ions were covered, including how to spot them and how they affect a molecule when they are attached chemically.
Students were asked to work on the following sheet,
and they were asked to circle the polyatomic ion in the molecules featuring polyatomic ions.
