An isolated neutron is unstable, so an isolated antineutron is also unstable. A neutron inside a nucleus is stable, so a antineutron inside an antinucleus is also stable.
16 neutrons in the most stable isotope of phosphorus (15P31).
A free neutron has a half life of just more than 10 minutes. But in a nucleus it seems stable enough. In modern terminology, it is made up of 1 UP and two DOWN quarks, and these between them have all the three colours.
There is only 1 proton and that proton does not have to be bonded to any other protons.
A neutron has a lifetime of about 15 minutes. This means that if you wait roughly 15 minutes there is a good chance the neutron will have decayed into other particles. So lone neutron just decay quickly, that is why there aren't any around. A neutron in an atomic nucleus is stable however (fortunately for us!).
Nuclei that have an excess of neutrons can become stable by emitting beta particles (electrons or positrons). This process helps the nucleus increase its neutron-to-proton ratio and achieve a more stable configuration.
The only stable isotope has 10 neutrons
They rotate with an amazingly stable rotation rate.
A glass with the composition CdO-SiO2-B2O3 forms a neutron absorbing glass which is quite stable against moisture attack and divitrification and are good slow neutron absorbers
The atoms having 2 protons only in nucleus is not stable but 2 protons with 2 neutron in Helium nucleus are very stable.

The atoms are stable when having the ratio of neutrons to protons that lie on the atom stability line. These stable atoms do not emit radiation as alpha, beta, neutron, or gamma radiation.

1 neutron in He-3 isotope. 2 neutrons in He-4 isotope (most stable)
Neutron emission from a nucleus can change the atomic mass of an element without affecting its atomic number. This can result in the formation of a different isotope of the element. Neutron emission can also make the nucleus more stable by reducing the neutron-to-proton ratio.
