Question

For nuclei of an element undergo fusion to form a heaviour nucleus, with release of energy. Which of the two - the parent or the daughter nucleus - would have higher binding energy per nucleon.

Answer 1

i am too having problem with this . but i wrote daughter nucleus .

Answer 2

A nucleus with higher mass is formed in nuclear fusion. For example, in the sun Hydrogen combines to form Helium. A nucleus with more mass has more mass defect than a nucleus of less mass. So in the example, Helium will have more mass defect than hydrogen. According to Einstein's equation, Helium would have more BE per nucleon. So the daughter nucleus would have higher binding energy.
