In beta-minus (β⁻) decay, a neutron inside the nucleus is converted into a proton, and a beta particle (electron) is emitted. Since a neutron is simply replaced by a proton, the mass number remains unchanged, though the atomic number increases by 1. This transformation preserves the total number of nucleons.
