        Ok, we've talked about Lewis Structures and we've talked about VSEPR. But wouldn't it be nice if we could practice them together on the same molecules? Covering one example of each of the six actual geometries available with two, three or four centers of electron density? You're in luck! Mr.Causey on VSEPR: http://youtu.be/-pq2wum1uDc

          2D Lewis Dot structures are really handy, but not quite representative of the actual shape in the 3D world. With a little more work you can make those flat structures come to life.

            Once you feel pretty good about the basics of Lewis Dot, you might want to dig a little deeper. Explore molecules with odd numbers of electrons, decide among multiple seemingly legitimate structures and deal with the polyatomic. All quite a lot of fun.

              The great chemist, Gilbert N. Lewis created a simple way to show how atoms in compounds (typically covalent) bond with each other. The trick to keeping it simple was to focus only on showing valence electron interactions. This video will show you the trick to writing Lewis (Dot) Structures correctly.

                So what happens when you run out of electrons in a Lewis Structure? You're going to have to break out the double and triple bonds. And that is exactly where they start getting fun. Tyler DeWitt reviews all things valence: http://youtu.be/yADrWdNTWEc

                      An way of determining the correct Lewis structure for simple molecules and ions is outlined. The topic of 'resonance' in molecules is also shown.
