Which of the following can be produced during the nuclear fission as well as nuclear fusion reactions?(a) protons (b) deutrons (c) electrons (d) neutrons
(d) neutrons
Explanation
During nuclear fission as well as nuclear fusion reactions, neutrons can be produced.
Nuclear fusion is the process by which two nuclei of light elements combine to form a heavy nucleus.
When deuterium atoms are heated to an extremely high temperature under extremely high pressure, two deuterium nuclei combine to form a heavy nucleus of helium, and a neutron is emitted. A tremendous amount of energy is liberated in this fusion reaction.
Reaction:
$_{1}^{2} \mathrm{H}+_{1}^{2} \mathbf{H} \stackrel{\text { fusion }}{\longrightarrow}\ _{2}^{3} \mathrm{He}+_{0}^{1} \mathrm{n}+ Tremendous\ amount\ of\ energy$
Nuclear fission is the process by which the heavy nucleus of a radioactive atom (such as uranium) splits up into smaller nuclei when bombarded with low-energy neutrons.
When the heavy nucleus of Uranium-235 atoms are bombarded with slow-moving neutrons, the heavy uranium nucleus breaks up to produce two medium-weighted atoms, barium-139 and krypton-94, with the emission of three neutrons. A tremendous amount of energy is produced in this process.
Reaction:
$_{92}^{235} \mathrm{U}+_{0}^{1} \mathbf{n} \stackrel{\text { fission }}{\longrightarrow}\ _{56}^{139} \mathrm{Ba}+_{36}^{94} \mathrm{Kr}+3_{0}^{1} \mathrm{n}+ Tremendous\ amount\ of\ energy\ (210MeV)$
