Are electrons particles or waves? Here’s the lecture from Wednesday. If you’re still having questions, not only watch this vodcast, but also you might watch the video clips we saw in class today. They’re in the Vodpod below – The Emission Spectrum of Hydrogen and Animated Quantum Mechanics. By the way – did you read the cartoon? :)

A couple of video clips we watched in class are in the VodPod collection below (you may have to open the entire collection): “The Electromagnetic Spectrum” and “Animated Quantum Mechanics.” They’d be great for review.

So who do you think is right – Neils Bohr or Louie deBroglie? Let’s talk more tomorrow and see what you think then. By the way, what did you think of the animated version of the double slit experiment? Corny, I know, but it really has a ton a great, very accurate information. I’ve put it in the Vodpod below, if you’d like to review it again.

Here’s the lecture from Wednesday on just that. Make sure you know the types of electromagnetic radiation and the uses of most of them (all except for long waves). By the way, I put your favorite “Electromagnetic Radiation Song” in the Vodpod collection below, if you’d like to watch it again…and again…and again. :) We’ll explore waves further tomorrow – make sure you bring a calculator to class tomorrow.

Did you know there is a baseball team called the Isotopes? No kidding, they’re a minor league team in Albuquerque, New Mexico. This is a pic of their “Isotope Field.” Go figure! Almost all elements have naturally occurring isotopes is some amount. Are you getting the hang of writing hyphen notation and nuclear symbols? We’ll finish working on calculating average atomic mass on Monday. Use the formula I gave you today to work those problems on the homework. How’s the carbon isotope project coming?
