Question and answer
what is the name for the length of time of a decay process ? how can this be used to calculate the amount of a radioactive element compared to its original amount?
Half-life is the period of time it takes for a substance undergoing decay to decrease by half. [ Half-lives are very often used to describe quantities undergoing exponential decay—for example radioactive decay—where the half-life is constant over the whole life of the decay. ]
