Section 1: Under 'Homework Documents' you will see two items; one is a video that I made for you and the other is a pdf file of a blank periodic table. The video is a swf. file, which means you need Adobe Flash to watch it, if you have an older computer you can just watch it in Internet Explorer, or you can download a swf opener (just google swf file opener and you should find several options).
Watch the video and then fill in the periodic table with the electron configurations blocked out for each section. You should also color code it. There is an example image in the video.
Also, in your notebook, write out the electron configuration for Lithium, Barium and Phosphorus. Don't worry about making a mistake - we will go over it tomorrow in class.

Thank You!
Gents-
Thank you so much for your generosity towards our 'T-giving $' fund. I was able to use the $57 in cash to buy 12 cartons of shelf stable milk, 10 can of chicken broth and 2 cans of canned fruit. I also donated over $10 in coins to the Campus Ministry office to help them fund service trips! I am so proud to be the teacher of such generous young men...way to go!
