# Carbon 14 disintegration

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 ?

The ionisation energy of a nitrogen atom is about 14.5eV but in $^{14}$C beta decay the electron is emitted with an energy of 156keV, which is far higher than the ionisation energy. So beta decay will normally produce an N$^+$ ion and a free electron.
