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, with atomic number 93, is a transuranic element that typically forms chemical bonds with a variety of other elements. Commonly, neptunium can bond with oxygen to form oxides such as neptunium dioxide (NpO2) and neptunium trioxide (Np2O3). Neptunium can also bond with halogens like fluorine, chlorine, and bromine to form neptunium halides. Additionally, neptunium can bond with various ligands in coordination complexes due to its ability to exhibit multiple oxidation states.
Neptunium is ductile and malleable; see also at: http://www.onemine.org/search/summary.cfm/Institute-of-Metals-Division--Fabrication-of-Neptunium237-Wire-by-Extrusion-TN?d=25FB0091D9A4A9A7F667E4C439E0ED9006727D6BC0570438EA2470D65AC3E9C126367
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.
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.
Promethium is not in the neptunium series of radioactive decay.
Neptunium itself is an element, the simplest form of matter.
Yes, neptunium can be mixed with other elements to form compounds and alloys. Neptunium is a radioactive element, and its compounds are primarily produced for research purposes. Various elements such as oxygen, fluorine, and hydrogen can combine with neptunium to form different compounds.
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.
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 radioactive metal that is not combustible under normal conditions. However, it can react with oxygen in the air to form oxides, which can be potentially flammable. Special precautions are taken when handling neptunium due to its radioactive nature.
