Could someone elaborate on half-life and its significance in this chapter? I have the equations to find half-life, but I'm confused about its relevance and application in the chapter.

You might be asked to calculate how much of a substance will be left after a specific amount of time has passed, in which case you could use the half life equation to answer

Half-Life is the time it takes for one-half of the atoms of a radioactive material to disintegrate. The "half" is an arbitrary amount that represents the amount disintegrated; it can be a "quarter-life" or a "fifth-life". It is useful in dating artifacts, treating patients, and calculating waste storage time.
