The exponential decay of a radioactive substance over time, showing the concept of half-life.

The strong force is the fundamental force that binds protons and neutrons together in the nucleus, overcoming electromagnetic repulsion between protons.

Mass-energy equivalence states that mass and energy are interchangeable, described by the equation $E=mc^2$, where a small change in mass can result in a large change in energy.

Nuclear fusion is the process where two light nuclei combine to form a heavier nucleus, releasing energy due to the mass defect.

Nuclear fission is the process where a heavy nucleus splits into two or more lighter nuclei, releasing a significant amount of energy.

Radioactive decay is the spontaneous transformation of an unstable nucleus into a more stable configuration, often accompanied by the emission of particles or energy.

Half-life ($t_{1/2}$) is the time required for half of the radioactive nuclei in a sample to decay.

The decay constant ($lambda$) represents the probability of a single nucleus decaying per unit time. It is related to half-life by the equation $\lambda = \frac{\ln 2}{t_{1/2}}$.

The splitting of a heavy nucleus into lighter nuclei, releasing energy.

The combination of light nuclei to form a heavier nucleus, releasing energy.

Spontaneous transformation of unstable nuclei into more stable configurations.

The time required for half of the radioactive nuclei in a sample to decay.

The probability of a single nucleus decaying per unit time, denoted by λ.

The fundamental force that binds protons and neutrons together in the nucleus, overcoming electromagnetic repulsion.
