The radioactive nucleus $^{214}_{83}\text{Bi}$ changes into a different nucleus when a $\beta$-particle is emitted. What are the proton number and the nucleon number of the nucleus produced in this decay?
- Aproton number $81$, nucleon number $210$
- Bproton number $81$, nucleon number $212$
- Cproton number $84$, nucleon number $213$
- Dproton number $84$, nucleon number $214$
