It appears that you have some confusion about the particle physics inside the nucleus. Nothing "separates protons so that the strong force can hold the nucleus together", the strong force acts via the exchange of particles called mesons.
The atomic nucleus contains particles called protons and neutrons. The strong force binds the protons and neutrons together via the exchange of particles called mesons between those protons and neutrons.
The electron is the particle not found in the nucleus of the atom. It orbits around the nucleus in specific energy levels.
The nuclear particle that has no charge is the neutron.
Nucleon.
The small, negatively-charged particle in an atom is an electron. However, this is not in the nucleus. The small negative particles in the nucleus are down quarks, which are smaller than protons and electrons. Strange quarks and bottom quarks are also negative, but are not found in the nucleus.
Electrons are the major type of subatomic particle that are not found within the nucleus of an atom. Electrons orbit the nucleus in energy levels and contribute to the atom's overall charge and chemical behavior.
The electron is the particle not found in the nucleus of the atom. It orbits around the nucleus in specific energy levels.
The Neutron and the Proton are to be found in the nucleus of an atom.
Protons and neutrons are found in the nucleus of an atom.
the electrons are found outside the nucleus. the nucleus contains protons and neutrons

The neutron is the subatomic particle that has no charge and is found in the nucleus of an atom. Neutrons play a key role in determining the stability and properties of an atomic nucleus.
