Beta-minus decay is a type of radioactive decay in which a neutron in the nucleus of an atom is converted into a proton, an electron (or beta particle), and an electron antineutrino. The proton remains in the nucleus, while the electron and electron antineutrino are emitted from the atom.
The equation for beta-minus decay is as follows:
$$n^0 \rightarrow p^+ + e^- + \overline{\nu}_e$$
In the case of carbon-14, the beta-minus decay process can be represented as follows:
$$_6 C^{14} \rightarrow _7 N^{14} + e^- + \overline{\nu}_e$$
