Why are neutrons needed in an atom?

Atoms never have two or more protons in their nucleus without having at least one neutron (or more). Protons don't like each other. They have a positive electrostatic charge, and like charges repel each other.So protons alone cannot make up an atomic nucleus.

Enter, the neutron When atoms are created by fusion, neutrons are included in the construction. They have to be.In fusion, the building blocks of a new atomic nucleus are "smooshed" together, and all of the particles undergo a mass change. Each nucleon loses a bit of mass, and that mass is converted into nuclear binding energy or nuclear glue.

And it is this stuff that makes the protons stick together (with the neutrons). It takes protons and neutrons to contribute to the creation of binding energy to cause a nucleus to fuse together The hydrogen-1 isotope (the most abundant form of hydrogen) has no neutrons, which is possible because it only has one proton.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
