How do you determine which beta decay occur spontaneously?

Beta decay occurs spontaneously in isotopes where the neutron-to-proton ratio is higher than what is stable, leading to the conversion of a neutron to a proton, electron, and antineutrino to achieve a more stable ratio. The decay is influenced by the weak nuclear force, which governs interactions at the subatomic level and can cause the transformation to happen spontaneously.
