CHEMISTRY: We made it! Here’s the very last lecture from chapter 6 – intermolecular forces. (Don’t forget they’re also called van der Waals forces!) Tons of application, from bugs walking on water to little fishes breathing dissolved oxygen!
CHEMISTRY: I’ll have to admit, this is a different way to decorate your walls! And now you know why it doesn’t wash away! Here’s our discussion of the why of a very important chemistry rule – and how you can apply it!
CHEMISTRY: So why is molecular geometry important? I mean why is knowing the correct shape of molecules? Here’s the beginning of the answer! Great job on drawing dipoles. We’ll continue the fun tomorrow!
CHEMISTRY: Great job with polyatomic ions and molecular geometry today! Who knew we’d be doing geometry in chemistry?!?
For tomorrow, be sure and print and read the cLAB: 3D Molecules! Advice for Lewis structures – don’t forget to count the electrons! And then double check the number of electrons. And when you think it’s right, count the electrons!! 🙂
Advice for molecular geometry? Make sure you know how to draw Lewis structures, then determine the type of ABE structure and you’ve got it. Easy-peazy!
Welcome to a great adventure! You’ve learned so much this year – not just concepts, but skills, and I can’t wait to see how you are going to apply it all!
Here’s the place where you can post your questions about the Lost Inside the Mponeng project so that everyone can see the answers.
First answer – the due date is Tuesday, April 30.
A really useful hint? Go back and re-read the project again – this time with a highlighter. It’s amazing how much I miss the first time I read something. So what’s your next question? 🙂

CHEMISTRY: Wow! Lewis structures, multiple bonds, and now resonance!
HW UPDATE: Homework that was scheduled for tonight has been moved to Thursday – due Friday. Thursday night’s scheduled homework is moved to Friday – due Monday.
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: Don’t you just love dots??
Great start on Lewis Structures! Practice, practice, practice. Warning: before you know it, you’ll be seeing dots everywhere!

CHEMISTRY: So how does it work when atoms share electrons? Sharing can hold something together? Here’s our discussion on covalent bonds.
CHEMISTRY: Ready to begin another chapter? What makes atoms “stick” together? Here’s the first lesson from chapter 6, the introduction to chemical bonds. Don’t you wish all the problems would be this hard?!
CHEMISTRY: Have you missed any of the discussion from the intro to each block in the Element Scavenger Hunt? This vodcast is for you!
Test Monday(!) and I’m going to let you use your Scavenger Hunt on the LAST ten minutes of the test (!) – so I thought I’d post TWO VERY IMPORTANT vodcasts to help you study for this part of the test. First is the beginning again – a history of the periodic table and the general notes on each block – some of this you may have seen before. Second vodcast is a final run through of slides – clarifying some information and filling in gaps you might have.
Amazing! Before you started the cLAB, did you every dream there was that much interesting and important stuff to know about the s, p, d, and f block elements?!
As you are studying, make sure you go back and practice figuring out the period, block, group, and type of element from the electron configuration. And don’t forget the topics I asked you to research for yourself that you will find on the Chapter 5 Stuff to Know Sheet on Edline!!
To make your research even more interesting(!), there are some really interesting videos with tons of useful information at this site: http://periodicvideos.com/
Some great videos to watch for the p-Block are carbon, nitrogen, oxygen, fluorine, and chlorine. http://periodicvideos.com/
