After taking and reflecting on the Atomic Structure and Radioactivity pre-test, I decided my first focus for this unit would be calculating half-life, since I already have a general understanding of it. This will help me learn it quickly and be able to move on to the more challenging topics in this unit. After doing some research, I found this helpful diagram that shows an example of half-life decay, by illustrating the decay of 544 grams of a substance that has a half-life of 1 day:
Doing research about half-life lead me to discover that there are three different types of half-life decay: zero, first, and second order reactions. The equation that you use to calculate half-life differs depending on the type of reaction. A very useful website to help me remember how to calculate each type is:
