Naming Binary Compounds

Theirs a reason that your supposed to read the textbook before you get to class. The first day in lecture, I didn't understand anything. My teacher started talking and it was in one ear, out the other. Anion, Cation, Ionic Compound didn't make a difference, I was clueless to what she was talking about. 

To be fair, by the look of a few of my classmates, I wasn't the only that was as lost as a fish out of water.Thankfully I had enough sense to go over the practice work that came out of the book, so I managed to do pretty well on the quiz.
