CHEMISTRY: Great job with polyatomic ions and molecular geometry today! Who knew we’d be doing geometry in chemistry?!? Be sure and print and read the cLAB: 3D Molecules for tomorrow!

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: At the beginning of this vodcast, some questions and answers from 2nd period about the project!
