NEET 2002 Physics question

Which of the following are suitable for the fusion process :

(1)Light nucleiCorrect
(2)Heavy nuclei
(3)Element must be lying in the middle of the periodic table
(4)Middle elements, which are lying on binding energy curve

Answer: (1)

Solution

In the binding-energy-per-nucleon curve, the binding energy per nucleon rises steeply for light nuclei and peaks near (Fe region). Fusing two light nuclei produces a heavier nucleus with greater binding energy per nucleon, so
