Hon Chemistry 11-27-17 Structure of the Atom

HON CHEMISTRY: Were you able to follow the connections the scientists made as they discovered the structure of the atom? Here’s the lecture from today. Do you think there could be anything smaller than protons, neutrons, and electrons? Hmmmmm……

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.

Don’t forget about the video clip we watched in class – and I’ve included a couple extra ones. they’ll help you review the different experiment that the guys like Thompson and Rutherford did. 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. Here’s the other one on The Discovery of the Nucleus.

By the way – how do you feel about playing scientist last week? How is what you did similar to the work of early scientists in discovering the structure of the atom?

Physics 11-27-17 Intro to Work & Energy

PHYSICS: Funny thing about words, all this work you thought you’d been doing, was it work after all?

Great intro to chapter 5! I think you’ll do great with the work problems, just remember everything from the last chapter and multiply by d!
