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?
Donβt worry! Today you learned all the background information about quantum numbers and what they mean. Tomorrow we will begin putting it all together π
Hon Chemistry 4-26-24 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 4-24-24 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! SUPER IMPORTANT – 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 – but better. I’m posting an overview from last year that has more examples than we were able to get to today. Bottom line? Memorize everything and practice everything! And did I mention, PRACTICE!! God bless you! I’ll be praying!!

Hon Chemistry 4-24-24 Electron Affinity, Ionic Radii & Electronegativity
HON CHEMISTRY: So you’re saying, not only are there atoms that want to get rid of electrons, there are atoms that want to take them? Here’s our super short lesson today on electron affinity, ionic radii, and electronegativity. I added more to it after you guys left.
Also the thumbnail photo on the vodcast is a picture of chlorine taking an electron from sodium – or sodium giving an electron to chlorine. I’ll let you decide!

Chemistry 4-23-24 Half Life Problems HW
CHEMISTRY: Great job thinking through the more challenging half life homework problems today! Were you listening…or are you learning?
Need some extra practice? Help session Thursday morning, 7:30 AM.
Hon Chemistry 4-23-24 Periodic Trends
HON CHEMISTRY: Hey guys, here’s our discussion of periodic trends – atomic radii, ionization energy, and second ionization energy. You made some great connections today!
Ducks and chemistry – who knew! π
Chemistry 4-22-24 Half Life
CHEMISTRY: Have these banana’s been through too many half lives for you?? Great job thinking through the half-life problems! Be sure and practice, practice, practice!
For homework, be sure and follow along with your notes! These problems aren’t super difficult, but if you don’t practice the right way, you’ll be as lost as a ball in high weeds!!
Hon Chemistry 4-18 & 19-24 Elements Occurrences & Uses
HON CHEMISTRY: Wow! Did you every dream there was that much interesting and important stuff to know about the s, p, d, and f block elements?! For Thursday and Friday, here’s our look at the s, d, f a& p 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!!
To make your research even more interesting(!), there are some really interesting videos with tons of useful information at this site: http://periodicvideos.com/ Go pop some popcorn and have some movie time!
The videos that you must watch from the s-block for the test are potassium, magnesium, and calcium.
The elements from the d block that I especially want you to watch are copper and mercury. And there are other interesting ones you might like to watch just for fun!
The element video from the f-Block that you need to watch is: uranium.
And the element videos you need to watch for the p-Block are carbon, nitrogen, oxygen, fluorine, and chlorine. http://periodicvideos.com/
For Thursday, Part 1
For Friday, Part 2
