Prof. Botch posted a nice summary of how to predict the charge of mono-atomic ions, and the composition of many covalent compounds. This can be a big help in making the transition from memorizing alot of compounds (as the book asks), to identifying some the trends that will help you predict formulas.

Not collected, but these are great problems to challenge yourself. Really good subjects for study groups. Answers are written in the form of a comment (below) – no peeking!
Fully worked-out answers can be obtained upon email request to any of the study group coordinators, or me, or Nag. But we’ll only send you one answer. To get more than one answer, you’ll need to find other students (hopefully with different answers!) or a study group.

No sound today. I tried to get better sound by plugging the wire into a jack on my computer -so naturally the wire was not connected to the microphone!
