Chemistry 1-7-13 Half-Life Problems

CHEMISTRY: Now here’s a healthy breakfast! So what do you figure is the half-life of a twinkie? Nooooooooo…..it’s not the same thing! (Even it you do eat it with a Red Bull!)

Since we were having technical difficulties, I’m posting a lecture from last year on how to work half-life problems. If you’re having some questions, this one may have a bit more explanation and a couple of extra sample problems at the end. Keep your notes beside you and keep thinking the problems through and you’ll do great!

Hon Chemistry 1-7-13 Noble Gas Notation

HON CHEMISTRY – Thank you so very much for being sooooo patient with the technology (and the teacher!) today!! I’m posting a copy of the lecture from last year. If you were having a bit of difficulty noble gas notation, this lecture will have a little more explanation.

Hey, how’d you do with reading electron configuration from the periodic table? Super cool, huh? And isn’t God awesome!?!
