A nucleus is stable only if the strong force can overcome the electrostatic repulsion. This is why heavier atoms require more neutrons (which provide extra "strong force glue" without adding repulsion) to remain stable. 3. Binding Energy and

When a nucleus has an unstable ratio of protons to neutrons, it undergoes to reach a more stable state. The three most common types are: Alpha (
The process of slamming light nuclei (like Hydrogen isotopes) together to form a heavier one (like Helium). This is the power source of stars, including our Sun. It produces far more energy than fission with less radioactive waste, though it is currently difficult to sustain on Earth. 5. Radioactivity and Decay
