Hydrogen is stable with no neutrons.
He3 and He4 are both stable. If the strong force were only 2% stronger, He2 would be stable.
Uranium has several stable isotopes, all with significantly more neutrons than protons.
The balance is governed primarily by how the strong nuclear force can overcome the electrostatic repulsion of the protons. Try making a scatter plot of stable isotopes vs. atomic number. That should be informative.

The number of protons and neutrons in a stable nucleus are the same. If they are not the same, it is called and isotope and is not stable.

The number of neutrons and protons are the same. They are the same as the atomic number. When there are a same amount of protons and neutrons, then the nucleus is stable.
Hope that helps!
