Question
Out of the two characteristics—the mass number (A) and the atomic number (Z) of a nucleus, which one does not change during nuclear α-decay?
Solution
For, nuclear alpha-decay, β = -1e0
Thus, the mass number (A) of the element ZXA does not change during the nuclear alpha-decay.
Thus, the mass number (A) of the element ZXA does not change during the nuclear alpha-decay.
