Q. In the given reaction $\ _{Z}X^{A} \rightarrow \ _{Z + 1}Y^{A} \rightarrow \ _{Z - 1}K^{A - 4} \rightarrow \ _{Z - 1}K^{A - 4}$ radioactive radiation are emitted in the sequence
A) $\alpha,\beta,\gamma$
B) $\beta,\alpha,\gamma$
C) $\gamma,\alpha,\beta$
D) $\beta,\gamma,\alpha$
Explanation
(b) $\ _{Z}X^{A}\overset{\ \ _{- 1}\beta^{0}\ \ }{\rightarrow}\ _{Z + 1}Y^{A}\overset{\ _{2}He^{4}(\alpha)\ }{\rightarrow}\ _{Z - 1}K^{A - 4}\overset{\ _{\ \ 0}\gamma^{0}\ \ }{\rightarrow}\ _{Z - 1}K^{A - 4}$
