CHEMISTRY: Great job with polyatomic ions and molecular geometry today! Who knew we’d be doing geometry in chemistry?!? No audio today, so I’ve found a lesson from last year, BUT start it at about 14 minutes.

For tomorrow, be sure and print and read the cLAB: 3D Molecules! Advice for Lewis structures – don’t forget to count the electrons! And then double check the number of electrons. And when you think it’s right, count the electrons!! 🙂

Advice for molecular geometry? Make sure you know how to draw Lewis structures, then determine the type of ABE structure and you’ve got it. Easy-peazy!

BONUS – kind of: At the beginning of this vodcast – til about 14 minutes, there are some questions and answers from last year about the project BUT it’s last year’s project. Still, some of the questions and answers might help!!
