Radioactivity and Decay

The quiz is a brief overview of the information that was covered in September. It is not very challenging so you should score above 85%. Study chapter 3 and 4 of the textbook and you should do just fine.

If you score less than 85% you need to go back and review the material. You will have a second attempt to improve your score. If you still score below 85% after two attempts make an appointment to see me.
