प्रश्न
Calculate mass defect and binding energy per nucleon of `"_10^20 Ne`, given
Mass of `"_10^20 Ne= 19.992397` u
Mass of `"_0^1H = 1.007825` u
Mass of `"_0^1n = 1.008665` u
उत्तर
Mass defect (Δm) = Mass of nucleons − Mass of nucleus
= (10 × 1.007825 + 10 × 1.008665)u - 19.992397u
= 0.172503u
Binding energy ΔE = 0.1725034 × 931 MeV
= 160.600 MeV
Binding energy per nucleon `(ΔE)/A = 160.600/20`
= 8.03 MeV

In a nuclear reactor, what is the function of:

The figure shows the plot of binding energy (BE) per nucleon as a function of mass number A. The letters A, B, C, D, and E represent the positions of typical nuclei on the curve. Point out, giving reasons, the two processes (in terms of A, B, C, D, and E ), one of which can occur due to nuclear fission and the other due to nuclear fusion.
Answer the following question.
Draw the curve showing the variation of binding energy per nucleon with the mass number of nuclei. Using it explains the fusion of nuclei lying on the ascending part and fission of nuclei lying on the descending part of this curve.
