Oxides of Period 3 lab next class. Period 2, I forgot to hand out the lab. You need to read through the lab so you are prepared for next class. I am posting it here and I have copies in the classroom for you if you stop by.
Homework: Chemical properties of elements in the same group discussion paper.
Watch the videos below about the alkali metals and the halogens. Write a ½ - 1 page discussion of the similarities and differences in the chemical properties of elements in these two groups. Specifically discuss the reactions of the Alkali metals (Li, Na, K) with water and with the halogens (Cl2, Br2, I2). And the Halogens (Cl2, Br2, I2) with halide ions (Cl-, Br-, I-).
On the other resources page see Periodic Table of Videos for great vids on specific elements if you would like.
Review topic 2 section 1. You should know all of that material. Read 2.2 in preparation for next class. Here is the p,n & e practice as well as the average atomic mass problems I said I would post.
We will begin Topic 2 next class. The text is posted on the text/readings tab, it wouldn't hurt to get a head start. I will post practice problems by the weekend.
The bonus question (posted below if you missed it) is due next class and will not be accepted late, if I even imagine that the work you hand me is not your own I will not grade it. Remember I am not a mean terrible monster. I know the test was a little to long, and will grade accordingly.
