Hon Chemistry 5-4-21 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 a picture of chlorine taking an electron from sodium – or sodium giving an electron to chlorine. I’ll let you decide!

Hon Chemistry 5-6-21 Multiple Covalent Bonds, Resonance & Polyatomic Ions

HON CHEMISTRY: Are your eyes playing tricks on you yet? 🙂 Great job working with multiple bonds with Lewis structures today! Here’s our discussion from on double and triple covalent bonds.

Be careful about getting too happy with double bonding – count electrons and don’t forget CONS. And what else? Oh yes, PRACTICE, PRACTICE, PRACTICE!

Hon Chemistry 5-4-21 Periodic Trends, Pt. 2 & Chemical Bonds

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.

Hon Chemistry 4-21-21 History of the Periodic Table & cLAB: Element Reverse Scavenger Hunt (s-block notes)

HON CHEMISTRY: Great start to a new chapter! I love that you are going to be learning to research some really cool stuff about the elements on the Periodic Table.

Here is the intro the the history of the periodic table and and your short intro to the cLAB: Element Reverse Scavenger Hunt. We’ll pick up with the s-block tomorrow!

Lost… Project Web Post Comment

I’m excited to read your projects and find out what you did to survive!! Did you do more than just survive the project? Here’s where you post you comment for the week.

Web post topic – What did you learn from the Lost… Project (this time only, discuss things not related to chemistry). What did God teach you through the project?

Go!

Lost in the Taklamakan – The Last Weekend!!!

I’m praying for you as you finalize working on your project this weekend. I believe in you! You can do it!!!

Lots of good questions and discussion in class today. I’ve posted a vodcast from one of the classes below. And click here for a copy of the Final Notes & Advice Sheet that we talked about in class
Here are a few hints and advice – lots more great stuff in that sheet!

1. Make sure you internally document everything! That includes anything you talk about. Also, make sure your illustrations have an internal documentation on them. (Yes, you have to have illustrations! If you don’t something’s wrong.)

2. As a chemist, you must talk about all 23 items – why they would be good to use or why you would not want to use them. NEVER say you had no use for the item. You will not get credit if you do.

3. Don’t wait to do your Works Cited page last. Do it before you finish the final draft of your paper. It takes a while to compile a Works Cited and if you don’t have one, I cannot accept your paper. It would be better to have a few mistakes in your paper than to not turn in a Works Cited.

4. Save as you go! Go ahead and save a copy of your latest rough draft in your Shared folder – label it rough draft for now. This way, if something happens in your drive or if your computer crashes at the last minute, I’ll be able to see that you have been working on your paper.

5. Get someone that you trust to read over your paper and check it against the project guideline sheet that I gave you – especially the Manuscript Form Checklist. They’ll be able to help you find things you might have left off.

You can do great things! I believe in you and I can’t wait to read your paper!

Hon Chemistry 4-12-21 Chapter 4 Overview

HON CHEMISTRY: God bless as you study for the chapter 4 test! Here’s our overview of the test and look back at some of the “problems” from the chapter.

Have you checked out the Chapter 4 Stuff to Know Sheet? Make sure you give yourself plenty of time to memorize the things you need to memorize so that you can apply them on the test. And practice, practice, practice, the problems and electron configurations. Did I mention that already?

What about applications for discussion? Photoelectric effect, spectroscopy, etc.? Another great idea for studying is to watch the videos that we watched in class, and others – super helpful as you study for the test!! Here are some of them:
Spectrum of the Stars (overivew of the results of the spectroscopy lab you did, shows the connection between our lab on spectroscopy and how we can identify elements), Emission Spectrum of Hydrogen (how we use it to know about the energy levels in an atom), Quantum Mechanics (about the roles of Bohr, Schrodinger, Heisenberg), and also Animated Quantum Mechanics.

God bless you as you study! I’ll be praying for you!!
