The strong nuclear force.
electrostatic forces
Protons are found in the nucleus of an atom, which is located at the center. Neutrons are also found in the nucleus along with protons.
The residual strong force. The strong force (or color force) is what holds quarks together to form protons and neutrons. The residual strong force then holds the protons and neutrons together in the nucleus.
Nucleus
The extra neutrons are needed to keep the attractive strong nuclear force within the nucleus greater than the repulsive electromagnetic force of the protons in the nucleus. With heavy enough nuclei eventually this fails.

The strong nuclear force acts only on neutrons and protons in the nucleus of an atom. The opposite would be a weak nuclear force.

Between protons and neutrons exist the residual strong force (nuclear force).

The strong atomic force holds protons (and neutrons) together in the nucleus.
It is called strong nuclear force.
Protons and neutrons together in the nucleus
In a small nucleus, such as oxygen, xenon, or any of the lighter elements, the strong force generated by the protons and neutrons is stronger than the repulsion between protons, and the nucleus holds together. In a larger nucleus, such as uranium, curium, or the heavier elements, the strong force isn't strong enough to hold it together, and the electromagnetic force pulls it to pieces.
