Radioactivity

First let's review using the periodic table... Find the #protons, #neutrons, #electrons and the electron configuration for: Helium, Carbon, Oxygen, Magnesium, Silicon, and Argon.

Lets look at your notes sheet…think of these 3 questions and try to answer them... What is radioactivity? What is radioactive decay? What do we use to measure radioactivity?

Let’s examine the 3 types of Decay before we look at a Geiger Counter Alpha, Beta, Gamma As you watch the video, fill in the info about each decay type. 0:45-1:45 https://www.youtube.com/watch?v=QCkdTfyDCS8
