beta decay process by which an unstable nucleus emits an electron
beta particle electron emitted from the nucleus in beta decay
fission process of splitting a nucleus into several smaller nuclei; process used to produce nuclear power
fusion two nuclei with low masses are combined to form one larger nucleus; occurs in the sun and stars
gamma ray high energy electromagnetic waves; emitted when alpha and beta decay occur
half life amount of time it takes for half the nuclei in a sample of radioactive isotope to decay to a stable isotope
nuclear energy energy converted from mass during a fission reaction
radioactivity process of nuclear decay in which the nucleus can give off matter and energy
