The fission of a heavy nucleus gives, in general, two smaller nuclei, two or three neutrons, some `beta-`particles and some `gamma-`radiation. It is always true that the nuclei produced.

Options

A. have a total rest-mass that is greater than that of the original nucleus
B. have large kinetic energies that carry off the greater part of the energy released
C. travel in exactly oppsite directions
D. have neutron-to-proton ratios that are too low for stabitity

Answer

B

Explanation

The nuclear fission defers from other reactions in three respects.
a. The nucleus is deeply divided into two large fission fragments or nuclei of roughly equal mass. The nuclei or fission fragments fly apart at greater and thus possess large kinetic energies that carry off the greater part of the energy released. b. The mass decreases is appreciable and hence large energy is realeased. c. Other neutrons called fission neutrons, are emiited in the process. Small amount of energy is released in the form of radiation.
