CHEMISTRY: Wow! You learned a lot today! Don’t we serve an awesome God?!? You probably knew the periodic table was really organized, but did you realize that it was THAT organized? Awesome!
Be sure and practice with the homework tomorrow night, and don’t forget to use the Aufbau “chart”!!!!
UPDATE: Lab change for tomorrow. Change to Emmision Spectra of Elements. Be sure and print it and bring colored pencils.

HON CHEMISTRY: Who knew we’d be doing geometry in chemistry?!? Great job today! Lewis structures, multiple bonds, resonance, polyatomic ions, and now molecular geometry. Wow, that’s a lot you’ve conquered in the last few days!!
Molecular geometry is super easy. Make sure you know how to draw Lewis structures, then determine the type of ABE structure and you’ve got it. Here’s a copy of Molecular Geometry Shapes – VSEPR handout. Be sure and memorize the shape and the ABE structure that goes with it. Easy-peazy!
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: Great job with electorn configuration notation today! No audio on the recording today, so I’m posting a lesson from last year.
Just when you were getting the hang of drawing arrows, I go and change it! But don’t you think writing electron configuration notation is a whole lot shorter than doing orbital notation? Don’t get me wrong, knowing how to do orbital is great for seeing how the electrons are paired, but this way is waaaay shorter!
Be sure and practice with the homework tonight, and don’t forget to use the Aufbau “chart”!!!!

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!
