Bonding Wrap-Up

The past two lessons have covered a great deal of territory. We have learned about three different types of bonding (ionic, covalent, and metallic). We have learned about the difference between molecular and network structures. And we have overlayed all of this onto our knowledge of elements and compounds.

The diagram below is an attempt to help you keep all of this information organized in your head. It is my best attempt at rendering all the different ways that atoms do or don't bond.

At this point in the course, you should be able to take any given formula and place it in the correct section of this diagram. Try the practice examples below. If you get through them all and need more practice, ask your instructor to give you additional formulas. There is no shortage of chemical substances out there to practice on!
