Hint: The chemical element uranium is silvery-white and metallic. There are 92 protons and 92 electrons in an atom of uranium, of which 6 are valence electrons. It is slightly paramagnetic in nature. Nuclear power plants, as well as the nuclear reactors that power ships and submarines, can be powered by uranium. In nuclear weapons, it can also be applied. Inhaling uranium compounds can cause damage to the kidneys of humans and animals.
Complete Step by Step Answer:
Nuclear fission is a nuclear reaction in which low-energy neutrons are used to break the nucleus of an atom into smaller nuclei. Uranium $^{92}{{U}_{235}}$ on bombardment with slow neutrons gets split into smaller nuclei of krypton-88 and barium-145 and three neutrons get released. This means it undergoes a nuclear fission reaction.
A large amount of energy is released during the process.
$^{92}U_{235}+ ^{0}n_1 \rightarrow ^{56}Ba_{145} + ^{36}Kr_{88} + 3^{0}n_1$
Correct option: (C) Fission reaction.
Note: Deuteron is a nucleus of deuterium. A deuterium is an isotope of hydrogen, consisting of one proton and one neutron. When two or more atoms come together to produce one heavier nucleus, the process is known as nuclear fusion. The energy released in nuclear fusion is much greater than the energy released during the nuclear fission reaction. So, both nuclear fusion and nuclear fission reactions are exothermic in nature. Unlike the reaction in which energy is absorbed during the reaction, it is known as an endothermic reaction.
