Question
Draw a graph showing the variation of binding energy per nucleon with mass number for different nuclei. Explain, with the help of this graph, the release of energy by the process of nuclear fusion.
✓
Answer
In case of nuclei of low atomic number, binding energy per nucleon is quite small; when fuse together, they form a nucleus of higher atomic mass and higher B.E./Nucleon, and hence, they release energy and become more stable.
