Happy Thanksgiving!

Enjoy your Thanksgiving!

You have no chemistry homework, but when you're DESPERATELY missing science, there's this:
True Facts: Chameleon
Or this:
Great Science Questions...Answered!
Or this:
Slo Mo Shaolin Warriors
OR THIS:
Will We Ever Run Out of Music?

You get the point...eat some turkey.. have fun.. think about the world around you... think about science...because....

Section 1: Complete the following in the packet I handed out in class today:
Page 1 - All
Page 2- 2, 3, 4, 7
Page 3- 11, 13, 14, 15, 17, 18, 19, 22, 23

And - STUDY your TRENDS!

Section 2: Complete the following in the packet I handed out in class today:
Page 1 - 1-4
Page 2- 2, 3, 4
Also, draw the formula for the following ionic compounds in your notebook:
1) Potassium sulfide
2) Magnesium nitride
3) Barium Oxide
4) Lithium Chloride

And - STUDY your TRENDS!

Sections 3, 6 & 7: Study your trends. The videos for the bonus questions are below. You may also want to consult the packet that I gave out in class to help you prepare for any bonus questions. DO NOT LOSE THAT PACKET - WE WILL USE IT WHEN WE RETURN FROM BREAK.

All: Here are some helpful videos:
Writing Ionic Formulas: Introduction
Writing Formulas with Polyatomic Ions

**Quality Ch. 5 Outlines can be found at the bottom of the page!**

*I'll be in 4K3 at 7:40 tomorrow*

Thursday, November 21

Sections 3: Watch and take notes on the following video:
Trends and Lewis Structures
Also, complete all worksheets given out during class today

Section 6: Watch the videos below so that you can complete the worksheets I handed out last class:
Writing Ionic Formulas: Introduction
Writing Formulas with Polyatomic Ions

My sincere apologies to Taylor Ene, as these videos do not include my voice.
Sorry for the delay! Also, here's the image from class:

Wednesday, November 20

Sections 1, 2, 6 & 7: Watch and take notes on the following video:
Trends and Lewis Structures

Section 3: Answer all of the following questions in your notebook:

1. Rank the following elements by increasing atomic radius: carbon, aluminum, oxygen, potassium.

2. Rank the following elements by increasing electronegativity: sulfur, oxygen, neon, aluminum.

3. Rank the following elements by increasing electron affinity: sulfur, oxygen, neon, aluminum.

4. Explain why fluorine has a higher ionization energy than iodine.

5. What is the relationship between atomic radius and ionization energy?

7. What trend in atomic radius occurs down a group on the periodic table? What causes this trend?

8. What trend in atomic radius occurs across a period on the periodic table? What causes this trend?

9. Indicate whether the following properties increase or decrease from left to right across the
periodic table.
a. atomic radius (excluding noble gases)
b. first ionization energy
c. electronegativity
d. electron affinity

10. Why do you think elements in the same family generally have similar properties?

Monday, November 18

All: Lab reports for each group are due tomorrow (outline can be found at the bottom of the page). I want one HARD copy (non-digital) from each group. Also, don't forget that the Science Research Project packet that I handed you in the beginning of the year is a great resource!

**We will have a QUEST next Tuesday (11/26) in all sections**

Tuesday, November 12

All: Below is the summary of all work to be completed while I'm away:

1) Test corrections should be done on loose-leaf, stapled to the front of your test and left in the box in the HMO by Friday.

2) Lab reports for each group are due on Tuesday (outline can be found at the bottom of the page). Also, don't forget that the Science Research Project packet that I handed you in the beginning of the year is a great resource!!

3) Periodic Trends project is due on Monday. Each project must include an outline of pages 150-164 in your textbook, and a visual representation of periodic trends. Please see the bottom of the page for more info.

Wednesday, November 6

All: Below you will find the problems that were on the board during class today. The answer key can be found under Homework Documents. PLEASE NOTE that you will not be given the equations on the test, only the constants. 

Other study tools can also be found at the bottom of the page. 

E=hv     c=λv

h = 6.6262 x 10^-34 J∙s

c = 3.0 x 10⁸ m/s

Happy Studying!
