How do neutrons keep protons together in an atom’s core if they don’t have a charge?

Question

Wouldn’t it make more sense if neutrons had a negative charge so the protons would be attracted towards it? Is it just the neutrons mass that keeps the protons together?

Answer 1

There are four fundamental forces of the universe: electromagnetism, gravity, and the strong and weak nuclear forces. You have considered magnetism and gravity, but not the other two.

The answer to your question is the Strong Nuclear Force. It keeps the nucleus of atoms bound to each other.
