Chemistry 1-22-18 Properties of Radioactive Isotopes

CHEMISTRY: So ordinarily it looks like just any old hunk of rock, but this is a picture of uranium ore under UV light. Pretty cool, huh?!? Here’s our beginning discussion of the unique properties of radioactive nuclides, and a head start at looking at nuclear equations.

Have you looked over the half-life simulation lab? It’s one of easiest labs you’ve done, but it does require that you READ the instructions on the syllabus and the website. If there is something you don’t understand, I’ll be glad to help!

Hon Chemistry 1-22-18 Quantum Numbers

HON CHEMISTRY: Great start on quantum numbers today! Wow, it was a lot. Confused yet?

Don’t worry – today you learned all the background information about quantum numbers, tomorrow we’ll put it all together and it will begin to make sense.

FYI – in case you didn’t catch them earlier, here are the video clips that we watched in class last week. You really may want to watch them again as you study for the test.
The Electromagnetic Spectrum (not the song!)
Emission Spectrum of Hydrogen
Animated Quantum Video is the one that explains all about why scientists began to believe that electrons could be acting as waves
Quantum Mechanics explains more about the role of the men we studied today in the development of the quantum model of the atom
