Mass Defect (not in book)
... When an isotope undergoes a nuclear decay, it moves toward the band of stability. For heavy nuclei (those with 84 or more protons), a main type of radioactive decay is alpha decay, which makes the nucleus lighter, and less highly charged. For nuclei above the band of stability (those with a neutron/ ...
