What units would you use to express a half-life?
items over time, such as atoms per second
mass over time, such as grams per minute
amount of time, such as minutes, hours, or years
volume over time, such as liters per minute
Please help me
The unit is usually seconds. But it really depends on the situation you are in. If you are talking about uranium-238, then you'll be talking about a half life in the billions of years. However, if you are talking about the half-life of a muon, then it'll be in seconds or microseconds.
