Test

So we had our unit test yesterday and it felt good, I finished rather quickly and then had time to go back and double check it all. I'm hoping for an A but more realistically a B would be perfectly fine by me. Will update when the grades go in.

3D Man

So toady we learned that sadly our simple Lewis structure isn't quite that accurate, so we learned today how to do diagrams in 3D, its not that much more complicated, just have to memorize a few shapes and rules. This website (if you can ignore all the spammy ads) does a pretty good job at explaining it. And here are a few pics we took in the library while practicing this.

Lewis Structure

Today was the fist lesson of the new unit, bonding, we learned about Lewis structure and other things today. Something actually interesting that I learned is that certain atoms can go above 8 electrons, these atoms are ones in the P block in and below group 3 however the most common expanders are Sulfur, Phosphorus, Xenon, and Krypton.

A good example of a common expander            

 (Phosphorus Pentafloride)          

Test

The last lesson we learned wasn't hard, basic stuff. I'm ready for this test i just need to know all the constants and remember Avraigados Number just incase there is an energy of a mol problem on there.
Edit I felt good about it i had 2 that  didn't have enough time for and a few I made dumb mistakes on I'm sure so I'm hoping for a B
