CHEMISTRY: Great start to a new chapter – did you realize we did that?! Here’s our discussion of the history of the periodic table and a look at the properties of the groups of the periodic table. Now let’s investigate some of these elements in lab tomorrow!
Hon Chemistry 5-3-24 Molecular Geometry HW & Intermolecular Forces, Pt 1
HON CHEMISTRY: So we’ve put it all together – Lewis structures, molecular geometry, dipoles, and bond type. Here’s our look at the homework worksheet. How’d you do?
After that, a beginning look at the importance of molecular geometry with solubility, and a beginning look at intermolecular forces. Lots of applications, from using peanut butter to get gum out of your hair to little fishes breathing dissolved oxygen. Let’s do more tomorrow!

Hon Chemistry 5-2-24 Dipoles
HON CHEMISTRY – So why is molecular geometry important? What’s the big deal about knowing the correct shape of molecules? Here’s the beginning of the answer! Great discussion today and great job on drawing dipoles. We’ll continue with intermolecular forces tomorrow!
HOMEWORK UPDATE: Covalent Bonds Worksheet – Honors, Pg 1 only

Chemistry 5-1-24 Electron Configuration & Blocks of the Periodic Table
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 5-1-24 Molecular Geometry
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 4-29-24 Electron Configuration Notation
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 4-29-24 Resonance & Polyatomic Ions
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 4-29-24 Orbital Notation
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!
Honors Chemistry 4-29-24 Lewis Structures & Multiple Bonds
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 4-26-24 Quantum Model of the Atom & Quantum Numbers
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 🙂
