| beta particle |
electron reated in the nucleus of an atom, relesed during decay |
| binding energy |
energy required to break up a nucleus into its component protons and neutrons |
| decay series |
sequence of steps by which a radioactive nucleus decays into a non radioactive nucleus. |
| half life |
