One reason for using a neutron as a nuclear bullet is that it isn't deflected by magnetic or electrostatic fields like a proton or other ion would be. About the only thing that will slow down or deflect (scatter), or stop (absorb) a neutron is an atomic nucleus. Neutrons have many times more penetrating power than protons.
Neutrons have no charge therefore their path is not affected by the charge of the atoms and molecules around them. This lack of charge also prevents them from being repelled from the target nucleus's positive charge. An electron would be attracted to the nucleus but would end up orbiting the nucleus with the other electrons which might repel it from the atom anyways.
For nuclear reactions to take place the projected particle(neutron or proton) must come close to the target nucleus to interact with it.
In case of protons, they can't come close to nucleus. Both protons and nucleus are +ve charged so repel each other. But neutrons have no charge on them so they are not repelled and come close to nucleus.
Note - similar charges repel, opposites attract.
I believe it's because a neutron has no charge.
Neutrons are not affected by the electrostatic repulsion, that keeps other protons away from the nucleus.
Being electrically neutral neutrons penetrate easily an atom.
The Nuclear Force is caused by the exchange of pions between the protons and the neutrons.
an attractive force that acts between protons and neutrons
The residual strong nuclear force.
Protons and neutrons together in the nucleus
These are the constituents of atoms. Nuclei are made up of protons and neutrons. Useful nuclear energy is only obtained from a few nuclei which can be made to fission and release energy. The two main ones are Uranium235 and Plutonium239.
Protons and Neutrons in atomb bombs are found in the nuclear fission reaction.
Protons, electrons, and neutrons are the subatomic particles that are involved in nuclear reactions.

The strong nuclear force acts only on neutrons and protons in the nucleus of an atom. The opposite would be a weak nuclear force.
The Nuclear Force is caused by the exchange of pions between the protons and the neutrons.
The Strong nuclear force is what holds the protons and neutrons together in an atoms nucleus. Think of a gorilla with an atom of two protons and two neutrons together and his hands holding the atoms together.

Protons and neutrons are bound together by strong nuclear force
Between protons and neutrons exist the residual strong force (nuclear force).
