We think that they are made of free particles and the cores may be composed of neutron degenerate matter. But we don't know for sure and it's fairly complicated. You can look up neutron stars on wikipedia for a better answer.
A neutron star is one that is entirely made up of neutrons.

The nucleus is made of protons and neutrons.
Atoms consist of protons, neutrons, and electrons. Protons and neutrons, in turn, are made up of quarks.Atoms consist of protons, neutrons, and electrons.

prorons and nuetrons are made up of quarks.
The nucleus is made up of protons and neutrons; the electrons form electron shells around the nucleus.
All atoms are made up of protons, electrons and neutrons (except for the 1H1 isotope, which has no neutrons)
Zero. Electrons are not made up of neutrons.
Atoms are made up of Protons and neutrons and electrons. Quarks make up Protons and Neutrons. Protons are made up of 2 up quarks and one down quark. Neutrons are made up of 2 down quarks and 1 up quark. A down quark has a charge of -1/3. An up quark has a charge of +2/3.
Zero. Electrons are not made up of neutrons.
Protons and neutrons are made up of three quarkseach.
Protons and neutrons are made of up and down quarks
