As the name suggests, neutron stars are actually composed of neutrons. When there is a sufficiently strong gravitational field, atoms (or superheated plasma consisting of fragments of atoms) collapse, and the electrons and the protons combine to form neutrons. Only neutrons are left.
It depends what you mean by "made". Neutrons pervade nature in all elements except hydrogen and were possibly "made" in nature in the early moments after the big bang from quarks and gluons coalescing once the temperature dropped enough for this to happen. If you mean made as in laboratory situations and for nuclear reaction purposes, a neutron heavy substance such as Uranium readily sheds neutrons as the neutrons contribute to the instability of the heavy uranium atom. So they are not really made, but "found" in a sense.
Nucleons are made up from quarks. Protons and neutrons each contain three quarks. We haven't been able to split a proton or neutron apart so its more of an idea of quarks based on evidence
There are several types of quark we name them on characteristics they give to a particle. Such as up, down, top, bottom, spin, charm and strange.
Nucleons (otherwise known as baryons when outside the atom) contain only up and down quarks
Proton: UUD
Neutron: UDD
antimatter is made up of antiquarks and follow a similar pattern to how matter is made up
Along with protons, neutrons make up the nucleus, held together by the strong force. The neutron is a baryon and is considered to be composed of two down quarks and one up quark.
A free neutron will decay with a half-life of about 10.3 minutes but it is stable if combined into a nucleus. The decay of the neutron involves the weak interaction as indicated in the Feynman diagram to the right. This fact is important in models of the early universe. The neutron is about 0.2% more massive than a proton, which translates to an energy difference of 1.29 MeV.
The decay of the neutron is associated with a quark transformation in which a down quark is converted to an up by the weak interaction . The average lifetime of 10.3 min/0.693 = 14.9 minutes is surprisingly long for a particle decay that yields 1.29 MeV of energy. You could say that this decay is steeply "downhill" in energy and would be expected to proceed rapidly. It is possible for a proton to be transformed into a neutron, but you have to supply 1.29 MeV of energy to reach the threshold for that transformation. In the very early stages of the big bang when the thermal energy was much greater than 1.29 MeV, we surmise that the transformation between protons and neutrons was proceeding freely in both directions so that there was an essentially equal population of protons and neutrons.
The composition of a neutron is said to be one up quark and two down quarks.
Free neutrons decay, giving off particles, which are a proton, and electron, and an electron antineutrino.
Neutrons are made of Quarks. More specifically, 1 "up quark" and 2 "down quarks."
Protons and neutrons are made of quarks and gluons.
Neutrons are made of subatomic particles called quarks

neutron
A sentence for neutron is:A neutron can be described as an uncharged elementary particle
as magnetic moments are created by the movement of electric charges Since the neutron is a neutral particle the magnetic moment is an indication of substructure i.e. the neutron is made of other electrically charged particles (quarks).There is a cloud of pi-mesons around the neutrons in result to the exchange of pi-mesons (the exchange particle of the strong force) with the other nucleons (proton and neutrons).the non-zero magnetic moment of the neutron indicates that it is not an elementary particle as it carries no net charge but still interacts with a magnetic field.The magnetic moment is negative which means that the neutron has a tendency to align anti parallel to a magnetic field rather than parallel to the field.
The neutron.
Neutrons are made of quarks (3 per neutron).
Both a neutron and a proton are made up of 3 quarks.Both a neutron and a proton are made up of 3 quarks.Both a neutron and a proton are made up of 3 quarks.Both a neutron and a proton are made up of 3 quarks.

It is made up of protons and neutron particles.

A neutron can be split up into 2 down quarks and an up quark.
its made from protons,neutron and electrons
No, a neutron star can't become a nebula. A neutron star is not made of atomic matter, has less mass than a nebula, and has no mechanism by which to expand.
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.
One : "The Adventures of Jimmy Neutron: Boy Genius" is the only one I know of .
Since neutrons are made up of three quarks, it's very safe to say the neutron is bigger.
Magnetars are a special type of neutron star.
