U-235
|
|
|
U-245
|
|
|
U-239
|
|
|
U-238

Explanation:
Detailed explanation-1: -Uranium-235 (235U or U-235) is an isotope of uranium making up about 0.72% of natural uranium. Unlike the predominant isotope uranium-238, it is fissile, i.e., it can sustain a nuclear chain reaction. It is the only fissile isotope that exists in nature as a primordial nuclide.
Detailed explanation-2: -As mentioned there, the essence of these reactions are their three characteristic steps: (1) initiation, (2) propagation, and (3) termination.
