HON CHEMISTRY 11-17-14b Structure of the Atom, Pt. 1

Posted on by

HON CHEMISTRY: Here’s the second part of lecture from Monday on how scientists began to determine the structure of the atom and the existence of subatomic particles – well, the electron anyway. FYI – as we go on, make sure you know the name of the scientists, the name of their experiments, be able to draw a diagram of their experiment, and describe how they interpreted the experimental results that led to their discoveries. Wow, that’s a mouthful!

Click here for the video on the Cathode Ray Tube Experiment that Thompson did, and also for a little history on The Discovery of the Electron. Do you think there could be anything smaller? Than an electron, I mean??

HON CHEMISTRY: Pretty impressive little theory that Dalton came up with, huh? Good job making comparisons with the Modern Atomic Theory. In addition, I want you now to be able show a connection between the three laws we discussed today and Dalton’s atomic theory

Chemistry 11-17-14 Mole Problems & Moles of Chalk Lab

CHEMISTRY: Awesome art! And great job on the moles of chalk lab! You set a land speed record for finishing a lab. Good job!

Here is a review of one of the mole problems. At the end of the vodcast, there are instructions for the lab, just in case you were out today. By the way, the lab can be written up on a sheet of paper – just make sure that you present your data and calculations like a scientist would!
