Question

Based on the information in the graph, why is energy released during the

fission of a uranium (U) nucleus?
A. The products have slightly more binding energy per nucleon, so
some mass is converted into energy.
B. The products are more stable than the uranium, so some energy is
converted into mass.
C. The products are slightly less stable, so some mass is converted
into energy.
D. The products have slightly more binding energy per nucleon, so
they are less stable than the uranium.

Answer 1

M0 = M1 + E

or E = M0 - M1

The difference between energy of the parent nucleus and the daughter nucleus (or nuclei) depends on the mass difference according the relation

E = M C^2

where E is the energy released when some of the original mass present is lost in the reaction
