What is mass-energy equivalence?

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.

Define nuclear fusion.

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

What is nuclear fission?

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

Define radioactive decay.

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

What is half-life?

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

Define decay constant.

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

Label the diagram of nuclear fission (Figure 1).

1: Neutron, 2: Uranium-235 Nucleus, 3: Barium Nucleus, 4: Krypton Nucleus, 5: Released Neutrons, 6: Energy

What does the Radioactive Decay Graph (Figure 2) illustrate?

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

Compare spontaneous and induced fission.

Spontaneous fission: Occurs without external triggers | Induced fission: Requires an input of energy, usually a neutron.

Compare nuclear fission and nuclear fusion.

Fission: Splitting of a heavy nucleus | Fusion: Combining of light nuclei.
