Four nuclei of an elements undergo fusion to form a heavier nucles, with release of energy. Which of the two - the parent or the daughter nucleus - would have higher binding energy per nucleon ?

As ligther nuclei are less stable than the intermediate nuclei, therefore, BE/nucleon of daugther nucleus will be higher than the BE/nucleon of parent nucleus. The difference in the masses of parent nucleus and daughter nuclei is the mass defect, which is released in the form of energy.
As the mass number A increases, the binding energy per nucleon in a nucleus.
Nuclear energy is released in fusion reaction, since binding energy per nucleon is
Nuclear energy is released in fission since binding energy per nucleon is
when two nuclei (A lt= 10) fuse together to form a heavier nucleus, the (a) binding energy per nucleon increases (b) binding energy per nucleon decreases (c) binding energy per nucleon does not change (d) total binding energy decreases
Assertion: The nuclear energy can be obtained by the nuclear fission of heavier nuclei as well as by fusion of lighter nuclei. Reason: As the mass number increases, the binding energy per nucleon, first increases and then decreases.
