HON CHEMISTRY: Can you guess what it is?/ It’s a picture of uranium ore under UV light. Cool, huh! Here’s the lecture from Thursday on the properties of radioactive nuclides and the types of radioactive decay. It also includes how to write nuclear equations. Don’t forget to memorize the nuclear symbols for alpha particles, beta particles (electrons), positrons, neutrons, and protons. Not nearly as bad as polyatomic ions, huh?!? 🙂

I thought you might want to get a head start on the half-life simulation lab, so I posted about that earlier. I’m including a copy of the Half-Life Simulation Lab here, but make sure you go back and read that post for detail that you will need. And speaking of half-life, let’s calculate it tomorrow. Calculators ready!
