Hon Chemistry 3-2-12 Intermolecular Forces

HON CHEMISTRY: Well, here it is, the very last lecture from chapter 6 – intermolecular forces. (Don’t forget they’re also called van der Waals forces!) Tons of application, from bugs walking on water to little fishes breathing dissolved oxygen.

Good luck studying for the test – have you practiced Lewis structures and drawing ionic bonding? Great idea!! And don’t forget www.sciencegeek.net. The Unit 3 section would be a great place to practice and check to see if you’ve learned what you think you’ve learned. I’ll be praying for you! You can do it!

And good luck with the 3-D Molecules Presentation! Holler if you have any questions. Don’t forget that if you are absent Monday, you can email it to me and I’ll put it on the server for you. Have a great weekend!

Chemistry 3-1-12 Periodic Trends, Pt. 2

CHEMISTRY: Wow! We finally finished the chapter!! Here’s the lecture from Thursday – second ionization energy, electron affinity, ionic radii, valence electrons and electronegativity. Lots of stuff to know, and lots of stuff to be able to apply!

Good luck studying for your test – you need to start that today! Have you checked out the Chapter 5 Stuff to Know Sheet on Edline? And don’t forget www.sciencegeek.net. The Unit 2 section would be a great place to practice and check to see if you’ve learned what you think you’ve learned.

Also, here’s a copy of the Chapter 5 Review Worksheet – which isn’t really a review worksheet, more of a sample test. Good luck studying! I’ll be praying for you!!
