想問大大
1.在高中時候教科書中的是那一種β衰變
2.β衰變不是有一個中子變為質子和電子，既然那個電子釋放左，點解個衰變物唔係變左陽離子既，因為質子是帶正電荷的
物理β衰變

✔ 最佳答案
1. The beta decay (β衰變) is a "beta minus"(β-) one that produces a high energy electron (高能電子) and an antineutrino (反中微子).2. There are plenty of free electrons (自由電子) present, the +ve ion would immediately be "de-ionized" by getting a free electron to its orbit and becomes a neutral atom.
