1.Explain why if a sample has a very short half-life, then it will be more radioactive than an element that has a longer half-life, any clues anyone?
Why are substances with shorter half-lives more radioactive?

SUMMARY
Substances with shorter half-lives exhibit higher radioactivity due to their rapid decay rates. For example, if a sample contains 1000 atoms of a radioactive element with a half-life of one hour, 500 atoms will decay within that hour. In contrast, an element with a half-life of two hours will only see 250 atoms decay in the same timeframe. This relationship between half-life and decay rate is fundamental in understanding radioactive materials.
