Examples: NpO2, NpCl3, NpF3.
The final product of the decay chain series of neptunium is thallium-205; the first product of decay is protactinium-233.
Neptunium is a chemical element. Atomic Number: 93, Atomic Symbol: Np. Neptunium is fissionable. For this, it is used as fuel in a fast neutron reactor or in a nuclear weapon. Neptunium is not a magnet.
Neptunium is a member of the actinides group.
The fresh surface of neptunium is silvery.
Neptunium is a chemical element with the symbol Npand atomic number 93.A metallic element, it does not have a color.
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].
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 contain atoms, not molecules.
The majority of neptunium characteristics are common to other metals.
Neptunium is not a common commercial product; it is under a strict control.
Neptunium is an artificial element; but significant amounts of neptunium are gathered in nuclear wastes from nuclear reactors, now without uses.
Uranium is more common and useful.
The final product of the decay chain series of neptunium is thallium-205; the first product of decay is protactinium-233.
There are no common compounds of argon. The only known compound is argon fluorohydride but that is hardly common. Also, argonium (argon hydride) molecules have been identified in the Crab nebula, but that can hardly be described as common.
Neptunium trifluoride is an intermediate for the preparation of neptunium metal.
sodium chloride, sodium carbonate, sodium bicarbonate
Neptunium is a metal.
