Carbon-14 is a radioactive isotope that emits beta-minus radiation.
Which nuclear equation shows how carbon-14 decays?
614C→714N+−10β^{14}_{6}\text{C} \rightarrow {}^{14}_{7}\text{N} + {}^{0}_{-1}\beta614C→714N+−10β
614C→514B+−10β^{14}_{6}\text{C} \rightarrow {}^{14}_{5}\text{B} + {}^{0}_{-1}\beta614C→514B+−10β
614C→410Be+24β^{14}_{6}\text{C} \rightarrow {}^{10}_{4}\text{Be} + {}^{4}_{2}\beta614C→410Be+24β
614C→810O+24β^{14}_{6}\text{C} \rightarrow {}^{10}_{8}\text{O} + {}^{4}_{2}\beta614C→810O+24β
