OK, so for next class you need to do the analysis and the challenge problems from the Topic 3 HW set. Also finish the post lab questions from the lab in class these are all (2-5) short answer style questions please try to be as thorough and articulate as possible.
Finally you need to do the group 1 and 17 video lab. Watch the videos linked below and the reactivity of the alkali metals and the halogens and write a 1/2 -1 page discussion of the similarities and differences in the chemical properties of the elements in these two groups. Specifically discuss the reactions of the Alkali metals with water and with the halogens and discuss the reactions of the halogens with halide ions.

Here is a fun video showing the reactions of the alkali metals with water, and another that is less exciting but a little more informative.
Here is a slightly boring but very informative video of the reactions between halides and halogens.
here is a video on sodium with the halogens. If you can find others that look at the other metals great!
