HON CHEMISTRY: Are your eyes playing tricks on you yet? 🙂 Great job working with multiple bonds and polyatomic ions with Lewis structures today!
Here’s some good advice – don’t take shortcuts. Learn the proper steps on the easier molecules, and you’ll be able to do the hard ones. And if it’s still all Greek to you, don’t worry! Keep practicing and you’ll get it, I promise!! Don’t forget to count electrons and don’t forget CONS!
CHEMISTRY: Wow, you did a great job today! Did quantum numbers begin making more sense when you started using them? Good work today on orbital notation. I think you’re going to be seeing arrows and numbers in your sleep!
HON CHEMISTRY – I just love dots! Incredible job today with Lewis structures!! Did we go too fast? Re-watch this vodcast for some great hints on making Lewis structures easier. And make sure you practice, practice, practice! Warning: before you know it, you’ll be seeing dots everywhere!
CHEMISTRY: Great job with quantum numbers today! Wow, it was a lot. Confused yet?
Don’t worry! Today you learned all the background information about quantum numbers and what they mean. Tomorrow we will begin putting it all together 🙂
HON CHEMISTRY: Hey guys, welcome to chemical bonds! How did you do on using electronegativity to determine bond type? Make sure you add the scale and also the diatomic molecules to your “things I have to memorize and know how to use for the test” list.

CHEMISTRY: God bless you as you practice for the test. Be careful and don’t take the test for granted! SUPER IMPORTANT – Use the Chapter 3A and the 21 Stuff to Know sheet as a guide for what you are memorizing and practicing.
Here is the test overview from today – but better. I’m posting an overview from last year that has more examples than we were able to get to today. Bottom line? Memorize everything and practice everything! And did I mention, PRACTICE!! God bless you! I’ll be praying!!

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 our super short lesson today on electron affinity, ionic radii, and electronegativity. I added more to it after you guys left.
Also the thumbnail photo on the vodcast is a picture of chlorine taking an electron from sodium – or sodium giving an electron to chlorine. I’ll let you decide!

CHEMISTRY: Great job thinking through the more challenging half life homework problems today! Were you listening…or are you learning?
Need some extra practice? Help session Thursday morning, 7:30 AM.
HON CHEMISTRY: Hey guys, here’s our discussion of periodic trends – atomic radii, ionization energy, and second ionization energy. You made some great connections today!
Ducks and chemistry – who knew! 🙂
CHEMISTRY: Have these banana’s been through too many half lives for you?? Great job thinking through the half-life problems! Be sure and practice, practice, practice!
For homework, be sure and follow along with your notes! These problems aren’t super difficult, but if you don’t practice the right way, you’ll be as lost as a ball in high weeds!!
