The half life of isotope #earthsciencerocks is 5 years. After 10 years, how much of the parent material remains?

1 answer:

3 0

After 10 years, the isotope would have had two half lives. For each half life, half of the material reacts. Therefore, after one half life, 50% remains. Then, after a second, 25% remains. D is the correct answer.
