Can you believe it?!? This is your LAST web post comment!! This is where you put it and here are the three things I want you to talk about:
1) How did chemistry grow you? What did you learn about yourself?
2) What advice do you have for future chemistry students?
3) What could we have done different this year that would have helped you learn chemistry better?
Can’t wait to hear from you!! 🙂
CHEMISTRY: Wow! We finished! Here’s our overview of the test and start to some test practice. First though, we took a look at some of the lab questions and answers. Good stuff for the test!
Have you checked out the Ch 4b & 5a Stuff to Know Sheet?? Make sure you memorize the things you need to memorize so that you can apply them on the test. And practice, practice, practice, the different kinds of electron configurations.
God bless you! I’m praying for you!!
HON CHEMISTRY: Molten iron, wow! Here’s our review of drawing ionic bonds and our discussion of ionic vs. covalent bonding, followed by metallic bonding.
Aren’t you glad there are no structures to draw for metallic bonds?! Make sure you can use the electron sea model to explain the properties of metals. Also be able to compare and contrast all three types of bonds.
HON CHEMISTRY: So how ’bout Johannes van der Waals and those intermolecular forces? Tons of application, from bugs walking on water to little fishes breathing dissolved oxygen. And what about the condensation that forms on the outside of an iced tea glass? Hmmm….
And then on to a different way that atoms come together – ionic bonding. Keep in mind that when you write ionic bonding, you’re not trying to arrange a single structure like you do with Lewis structures. Instead, you’re writing an equation that shows electrons being lost by one atom and gained by another atom. And make sure you put the dots in the right order!

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: 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!

CHEMISTRY – Great job with noble gas notation today!! Watch this vodcast again and it will make even more sense the second time! It would also be great review for the test! Speaking of which – have you checked out the stuff to know sheet for the test??? Super important!!!
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: 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!
