which statement accurately describes a half - life? a rock’s size is determined by half - life. all stable and unstable elements have a half - life. an atom of an element becomes half its original size in a half - life. a half - life is the time required for half of a radioactive element to decay.
Answer
Brief Explanations:
La vida media es el tiempo necesario para que la mitad de los átomos de un elemento radiactivo decaigan. Las otras opciones son incorrectas: el tamaño de una roca no está determinado por la vida media, solo los elementos inestables tienen vida media y no es el tamaño del átomo lo que se reduce a la mitad en una vida media.
Answer:
A half - life is the time required for half of a radioactive element to decay.
