Hon Chemistry 5-6-22 Molecular Geometry & Dipoles

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 and dipoles. 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!

Dipoles take a second to think about, but you can do this! 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!

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 5-6-22 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. Monday we will begin putting it all together 🙂

Here the video clip from today that shows the connection between electrons as particle and electrons as waves. It’ll be very helpful as you study!!

Animated Quantum Video is the one that explains all about why scientists began to believe that electrons could be acting as waves

Hon Chemistry 5-5-22 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!

Honors Chemistry 5-4-22 Lewis Structures & Multiple Bonds

HON CHEMISTRY – I just love dots! Incredible job today with Lewis structures!! If you were absent, be sure and 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!

Hon Chemistry 5-3-22 Intro to Chemical Bonds & Covalent Bonding

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 5-3-21 Chapters 3A & 21 Test Overview

CHEMISTRY: God bless you as you practice for the test. Be careful and don’t take the test for granted! 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. Bottom line? Memorize everything and practice everything! And did I mention, PRACTICE!! God bless you! I’ll be praying!!

Physics – Your LAST Web Post Comment!!

PHYSICS: 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 physics grow you? What did you learn about yourself?
2) What advice do you have for future physics students?
3) What could we have done different this year that would have helped you learn physics better?

Can’t wait to hear from you!! 🙂

Chemistry 4-29-22 Applications of Radioactivity, Pt. 2

CHEMISTRY: Hey guys! Here’s our discussion from Friday. More information on the applications of radioactivity

Have you started studying? The test will be Tuesday, May 3. Be careful and don’t take the test for granted! And don’t forget to check out the the Chapter 21 Stuff to Know & sheet.

Make sure you keep practicing half-life problems and nuclear equations. Also, make sure you’ve memorize the nuclear symbols for alpha particles, beta particles, positrons, neutrons, and protons. And then there are tons of notes on the conceptual stuff. Properties of radioactivity, people, types of radioactive decay, applications of radioactivity, definitions, definitions, and definitions!

Chemistry 4-28-22 Applications of Radioactivity, Pt. 1

CHEMISTRY: Radioactivity all around! Here’s the lecture from Thursday, the first part of our discussion on the applications of radioactive isotopes. We’ll talk about more applications tomorrow.

Are you ready for the test? The test will be next Tuesday, May 3. Be careful and don’t take the test for granted! Make sure you got a copy of the Chapter 3A and the 21 Stuff to Know & Study Suggestions sheet to help you get organized as you study.

Memorize everything and practice everything! And did I mention, PRACTICE!!
