Neptunium is an artificial element; but significant amounts of neptunium are gathered in nuclear wastes from nuclear reactors, now without uses.
The three common compounds of neptunium are neptunium dioxide (NpO2), neptunium trichloride (NpCl3), and neptunium tetrafluoride (NpF4).
Neptunium contain atoms, not molecules.
Neptunium has not minerals. It is an artificial element and in the nature is very rare, in some uranium ores.
The majority of neptunium characteristics are common to other metals.
Neptunium is not a common commercial product; it is under a strict control.
Neptunium(IV) oxide or neptunium dioxide is the chemical compound composed of neptunium and oxygen with the formula NpO2. It forms dark olive[4] green cubic crystals[1].
Uranium is more common and useful.
- 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 trifluoride is an intermediate for the preparation of neptunium metal.
Neptunium is a metal.
For the most common isotope of neptunium, Np-237, the decay daughter is protactinium-233.Each isotope has another type of decay.
Neptunium is an individual element; isotopes of neptunium are not separated.
