A nucleus of magnesium changes into a nucleus of sodium by releasing a $\beta^+$ particle. The transformation is shown by the equation below. $^{23}_{12}\text{Mg} \rightarrow {}^{P}_{Q}\text{Na} + {}^{0}_{+1}\beta$ Which values are $P$ and $Q$?
- A$P = 22,\; Q = 11$
- B$P = 22,\; Q = 13$
- C$P = 23,\; Q = 11$
- D$P = 23,\; Q = 13$
