A nuclear reaction where a nucleus splits into two smaller nuclei, releasing energy.

The symbol for an alpha particle is \( \text{ } ^4_2\text{He} \text{ } \).

Nuclear fusion.

An alpha particle.

An electron emitted from the nucleus during radioactive decay.

A nuclear reaction where two light nuclei combine to form a heavier nucleus, releasing energy.

A type of radioactive decay where an unstable nucleus releases energy in the form of gamma rays.

A positron is the antimatter counterpart of an electron, with the same mass but a positive charge.

Fission is the splitting of a nucleus, while fusion is the combining of nuclei.

Neutrons can initiate fission reactions and are also produced during fission.
