1. What is the mass number of the particle emitted from the nucleus during beta minus (B-) decay?

1 answer:

5 0

In beta-minus decay, a negative electron is emitted which produces a daughter nucleus of one higher atomic number but mass number remains the same.
For example:
The decay of the uranium product produces thorium-234 into protactinium -234.
