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?

Donโ€™t worry! Today you learned all the background information about quantum numbers. Monday we will begin putting it all together ๐Ÿ™‚

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
