When $\beta^-$ disintegration happens to a Carbon 14 atom, a neutron "turns into" a proton, and an electron is emitted. Therefore the result of the disintegration is a Nitrogen atom plus an electron (also an electron antineutrino, but that's not relevant here). My question is : is the nitrogen atom ionized ? Since it has $7$ protons, it needs $7$ electrons to be electrically neutral, but it only has the $6$ ones that the Carbon atom had, so it should have a supplement positive charge, shouldn't it ? Or does the emitted electron stay with the nitrogen atom so that it's neutral ?
