The proton, electron, and the antineutrino move away from one another emitting the electron as a beta particle. The process is summarised by the equation: \(_0^1n\rightarrow_1^1p+_{-1}^{\,\,\,\,\, ...

This changes a neutron into a proton plus an electron. The proton stays in the nucleus and the electron leaves the atom with high energy - we call it a beta particle. This is written as ...
