Today we discussed Lab #6, which is the preparation of Alum from Scrap Aluminum. This lab is a prototypical application of calculating theoretical vs. actual yields.
We then discussed how to look at the periodic table to determine the energies of the orbitals and we started to populate these orbitals. Electron counting rules are given as a guide, but we discussed the various exceptions to these rules. We Finished class by discussing the electron configurations of ions and the octet rule. This explains why certain ions want to have the charges they do.
