Isotope of the original nucleus is produced

Vedclass · Answer

(B) In $\alpha$ decay, the atomic number $Z$ decreases by $2$ and the mass number $A$ decreases by $4$. In $\beta^-$ decay, $Z$ increases by $1$ and $A$ remains constant. In $\beta^+$ decay, $Z$ decreases by $1$ and $A$ remains constant.An isotope has the same atomic number $Z$ but a different mass number $A$. Since $\alpha$ decay changes $Z$ and $\beta$ decay changes $Z$, neither process can produce an isotope of the original nucleus. Thus, the correct answer is that an isotope of the original nucleus cannot be produced.

For the radioactive nuclei that undergo either $\alpha$ or $\beta$ decay, which one of the following cannot occur?
