which statement accurately describes a half - life?\no a rocks size is determined by half - life.\no all stable and unstable elements have a half - life.\no an atom of an element becomes half its original size in a half - life.\no a half - life is the time required for half of a radioactive element to decay.
Answer
Brief Explanations:
Half - life is a concept in radioactivity. It is the time for half of a radioactive element's atoms to decay. Stable elements do not decay and thus have no half - life. Half - life has nothing to do with the size of a rock or an atom's size.
Answer:
A half - life is the time required for half of a radioactive element to decay.
