Since a Neutron has no electrical charge, does it do anything in an Atom?  Thanks for comments.  Joe L. Ogan

It overcomes the tendency of the nucleus to fly apart under the magnetic repulsion of one proton to another.

Electric, not magnetic.

A "strong force" acts between nucleons (that is, between 2 protons, between 2 neutrons or between a proton and a neutron); for complicated reasons (due to other quantistic properties of the nucleons) a nucleus made of only protons would be unstable and you have to put (Very approximately!) two neutrons every proton to make it ~ stable.
