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!!

Hon Chemistry 2-8-12 Electron Affinity

HON CHEMISTRY: So you’re saying, not only are there atoms that want to get rid of electrons, there are atoms that want to take them? Here’s the lecture (or an old remix, I should say) on 2nd ionization energy and electron affinity.
