Yes, the isotope 237Np, radiochemically pure.
- intermediate in the preparation of plutonium 238 - in the instruments for the detection of high energy neutrons - possible use in the future as material for nuclear weapons - possible use in the future as nuclear fuel
Neptunium is an artificial chemical element. Neptunium can be found in the nature only in ultratraces resulting from nuclear weapons experiments, radioactive wastes from nuclear reactors or from other experiments. Neptunium is found also in extremely low concentrations in uranium ores.
It all depends on mass. If its over the point of where a neutron star can form then it forms a black hole. If its below it then it'll form a neutron star.
A black hole.
While it the atmosphere of nepune does contain a lot of flamable hydrogen it contains relatively little oxygen, which is needed for hydrogen to burn. So if you were to light a match on Neptune the match would simply go out.
Neptunium is a solid metal.
Neptunium itself is an element, the simplest form of matter.
Promethium is not in the neptunium series of radioactive decay.

Any element; neptunium can form himself a critical mass.

Uranium 238 is bombarded by neutrons, and forms Neptunium 238. Neptunium decays to form Plutonium 238.

Neptunium is a metal, and therefore it can in theory form all the usual kinds of compounds that metals form; it could combine with oxygen and form neptunium oxide. However, neptunium is a radioactive element with a very short half-life, therefore it does not stick around long enough to engage in chemical reactions, or even if it did, the resulting compound would also exist only for a very brief period of time.
RAdio Detection And Ranging
The final product of the decay chain series of neptunium is thallium-205; the first product of decay is protactinium-233.
