Monday, October 4

Today we began Mr. Henderson's class by looking at Friday's blog post. Then talking briefly about the web-assign that was due Monday. Then we reviewed how to determine the number of protons, number of neutrons, and the element name based off the following: (To the left)

Then we proceeded by doing lab #AM15. We conducted a series of experiments that we used to determine if a an unknown substance was a metal, nonmetal, or metalloid. We organized our data into a chart and determined the physical and chemical properties of substances A, B, C, D, E, F, G, and H. However when doing the assignment we didn't find the chemical reaction of CuCl2 (Copper Chloride), but instead repla

ced it with HCl2 (Hydrochloric Acid).

After filling out the data section, we proceeded to take a 20 minute quiz on the material which we covered last week.
