From Friday – here’s the lecture on oxidation numbers. Lots of good practice at the end.  Hope the practice in the computer lab Thursday helped. Go back to sciencegeek.net

Here’s the lecture from Wednesday on writing formulas and names for binary molecular compounds. Part of it’s really similar to what you learned to do yesterday for ionic compounds, but another part is totally different.

Make sure you keep everything straight. Do something that will organize all the information for you, so you won’t get confused. Also, don’t forget the lists you have to memorize – polyatomic ions, numerical prefixes, and tomorrow or Friday I’ll tell you about acids. And practice, practice, practice!!!

It’s alot, but you can do it! Be careful!! Have your notes beside you as you get started so you can remember all the little pesky rules. And keep practicing! :)

Here’s the lecture from Tuesday. Today we concentrated on ionic compounds, tomorrow we’ll do molecules.
