WebAn isotope is an atom of an element with a different number of neutrons. For example, hydrogen (H) always has 1 proton in its nucleus (the atomic number), but the number of neutrons can vary among the isotopes (0, 1, 2). Recall that the number of neutrons added to the atomic number gives the atomic mass. brickhouse coffee roastersWeb11. After 5 half-lives have passed, the amount of parent isotope remaining is 3.13%.
