HON CHEMISTRY – I just love dots! Incredible job today with Lewis structures!! Make sure you practice, practice, practice! Warning: before you know it, you’ll be seeing dots everywhere!
CHEMISTRY: Today you’ll be practicing nuculear decay equations at The Physics Classroom.
Do the Apprentice, Master, and Wizard levels of the Concept Builder called Nuclear Decay. If you don’t finish in class, the rest of the assignment is for homework and is due at 8:00 A.M. Friday morning.
Be sure and write the equations for Level 3 on notebook paper. It will take you tons more time if you try to do it in your head!!
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 a picture of chlorine taking an electron from sodium – or sodium giving an electron to chlorine. I’ll let you decide!

HON CHEMISTRY: Here’s the last of the trends – not car trends, periodic trends! 2nd ionization energy, electron affinity, ionic radii, and electronegativity. Whew!
Now on to the next chapter and welcome to chemical bonds! How did you do on using electronegativity to determine bond type? Make sure you add the scale to your “things I have to memorize and know how to use for the test” list.
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!! 🙂
HON CHEMISTRY: Hey guys, here’s the first lecture on periodic trends – atomic radii and ionization energy. You made some great connections today!
Ducks and chemistry – who knew! 🙂
CHEMISTRY: God bless you as you practice for the test. Friday will be here before you know it, so 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!!

CHEMISTRY: We did it! Here is laaaaassst set of notes on chapter 21. If you have been absent, be sure and watch the vodcasts – we talked about information that isn’t in the textbook and also there’s a lot of good practice!!
Are you ready for the test? The test will be next Friday, May 7. 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!! God bless you! I’ll be praying!!
CHEMISTRY: Hey guys! Here’s our discussion from Thursday. The Lord willing, we’ll finish the chapter tomorrow. Also, don’t forget two special things due tomorrow!
Have you started studying? The test will be next Friday, May 7. 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!
