The binding energy per nucleon for the parent nucleus is E1 and that for the daughter nuclei is E2. Then what is the relationship between E1 and E2?
E2>E1
E2=2E1
E1=2E2
E1>E2
Solution:
After decay, the daughter nuclei will be more stable hence binding energy per nucleon will be more than that of their parent nucleus. Therefore, E2 > E1.
