Answer:
True
Step-by-step explanation:
The following two isotopes of Uranium which are prominently used in a nuclear chain reaction.
a) Uranium-233
b) Uranium-235
Uranium 235 consists of 92 protons and 143 neutrons. When an excited electron hits a Uranium atom, it splits into two smaller atoms and release heat energy under the process of fission.
There is another isotope of Uranium i.e Uranium -238, but it does not break easily and hence is less preferred for a nuclear reaction.
Thus, it can be said that the statement "lsotopes of uranium are used as nuclear fuel in power plants." is true.
