Neutrons are required. Atomic Radiation, Nuclear Graphite, and Effects
The fission reaction is often started by an impinging neutron, and each fission produces an average of 2.5 neutrons.
With the exception of the hydrogen nucleus, which has a single proton, neutrons are necessary for the stability of nuclei. Nuclear fission and fusion generate a tonne of neutrons.
Scattering tests and research on nuclear binding energies provide evidence for the nuclear forces' finite range. The neutron-proton (n-p) potential energy map in Figure 44.3a, which was created by scattering neutrons from a target containing hydrogen, illustrates the short range of the nuclear force. The n-p potential energy well is 40 to 50 MeV deep, and the nucleons are prevented from getting much closer than 0.4 fm by a strong repulsive component.

We need to add one neutron to initiate the fission reaction.
What are nuclear reactions?
The reaction in which the identity or characteristics of an atomic nucleus change due to the bombarding of it with an energetic particle is known as a nuclear reaction.
The bombarding particle can be an alpha particle, a gamma-ray photon, a neutron, a proton, or a heavy ion.
What is nuclear fission?
In nuclear fission, an atom splits into lighter nuclei due to the bombarding of an energetic particle.
The reaction given is
[tex]_{92}^{235}U + .... _{0}^{1}n \rightarrow _{52}^{137}Te + _{40}^{97}Zr +_{0}^{1}n[/tex]
To find the number of neutrons we have to balance the reaction
Atomic mass on reactant side = 235 + 1 = 236
The atomic number on the reactant side = 92
Atomic mass on the products side = 137+97+2 = 236
The atomic number on the products side = 92
As the reaction is already balanced
We need to add one neutron to initiate the fission reaction.
