Chemistry 1-17-20 Intro to Radioactivity

CHEMISTRY: Great start to a new chapter! I think you’ll be surprised how much nuclear chemistry is already a part of your everyday life. Also now you know where E=mc2 came from!!

By the way, you ought to read about the life of Marie Cure when you get a chance. Fascinating woman of science with an incredible story!

Hon Chemistry 1-17-20 Orbital Notation & Electron Configuration Notation

HON CHEMISTRY: Wow, you did a great job today! Did quantum numbers begin making more sense when you started using them? Good work today on orbital notation. I think you’re going to be seeing arrows and numbers in your sleep!

And then, just when you were getting the hang of drawing arrows, I go and change it! But don’t you think writing electron configuration notation is a whole lot shorter than doing orbital notation? Don’t get me wrong, knowing how to do orbital is great for seeing how the electrons are paired, but this way is waaaay shorter!

Be sure and practice with the homework tonight, and don’t forget to use the Aufbau “chart”! Let me know if you figure out the riddle!!
