Question

Quizplus · Accepted Answer

The forces that bind protons and neutrons together in the nucleus (called nuclear forces) are strong, but they can become overwhelmed by repulsive forces between protons, especially in heavier elements. This can cause the nucleus to become unstable and break apart, resulting in radioactivity. None of the other choices describe the mechanism behind nuclear decay.
