Day 137: Atomic Spectra

So, I'm finding the end of the year coming, and I'm actually in a good place. We're going to finish early. We'll have lots of time to review.

I don't think I've ever had that thought before. 

We talked about atomic emission spectra. Of course, I didn't have the tubes ready today (I'll have them tomorrow) so we didn't get to do a lab with it. Still, I could show pictures of the sun's spectrum and its dark lines.

We figured out how to model atomic transitions. The best question was about how this model is similar to and how it different from the model of the photoelectric effect. We talked a lot about the differences of the atoms and what happens to the electron.
