In chemistry class today, we took a pre-test over atomic structure and radioactivity. I knew very little, but I was surprised that I actually did know how to calculate the answer to a couple of the half-life questions. I remember this information from past science classes such as Earth Science. Some of the things I have never learned about before include all the different types of radiation and decay. I recognized the terms, but did not know what they meant. Throughout the next three weeks, during this unit, I hope to learn these terms and how to apply them to solve problems, so that way I can be much more successful on the actual unit test, compared to this pre-test. After the test, I did some research about some of the questions that I saw on the test, and I found some websites that might be helpful to look back on during the unit. You can find them here:

Types of Radiation
-
Types of Decay
Also, here is a very helpful picture to illustrate the penetrating powers of the different types of radiation:

Carly, I had the same feelings about the pre-test. Also, now that you mentioned it, I remember that we learned how to calculate half-life in 8th grade. Like you, I was able to calculate some half-life questions, but had forgotten where I had learned how to do it. I tired to find your helpful links on your post and couldn't find them. Is there anyway that you could please re-post them? I'm sure they're helpful and I could use them for learning more about the unit too.
