Q. The binding energy per nucleon for the parent nucleus is $E_{1}$and that for the daughter nuclei is $E_{2}.$ Then
A) $E_{2} = 2E_{1}$
B) $E_{1} > E_{2}$
C) $E_{2} > E_{1}$
D) $E_{1} = 2E_{2}$
Explanation
(c) After decay, the daughter nuclei will be more stable hence, binding energy per nucleon will be more than that of their parent nucleus.
