What is neptunium melting point?
644 °C
Neptunium/Melting point
What properties does neptunium have?
Neptunium is a ductile, silvery, radioactive metal. Neptunium forms numerous chemical compounds. Chemically it is extremely reactive and is attacked by oxygen, steam and acids, but not by alkalis. It can exist in many oxidation states, from neptunium (II) to neptunium (VII).
What are the properties and uses of neptunium?
While neptunium itself has no commercial uses at present, it is used as a precursor for the formation of plutonium-238, and in radioisotope thermal generators to provide electricity for spacecraft. Neptunium has also been used in detectors of high-energy neutrons.
How is neptunium used in everyday life?
Neptunium has only been considered, not actually used, as a fissile nuclear fuel. However, neptunium-237 is used to create plutonium-238, which is then used in special energy generators that can power satellites, spacecraft and lighthouses for a long period of time.
Is neptunium a conductor of heat or electricity?

Does the human body use neptunium?
Neptunium has no known biological role. It is toxic due to its radioactivity. Neptunium is obtained as a by-product from nuclear reactors. It is extracted from the spent uranium fuel rods.
Why is the element neptunium so important?
Neptunium remains an important element to study because it is produced by nuclear reactions of uranium and plutonium and can last as harmful radioactive waste for millions of years, according to a 2003 report by the Pacific Northwest Nuclear Laboratory.
How is neptunium harmful to humans and animals?
It occurs in traces and does not have any biological role. Studies show that it is not absorbed by the digestive tract of animals and if it concentrates in the bones then it gets released slowly. Powdered neptunium metal possesses fire hazards as it is pyrophoric. Its small pieces can easily ignite spontaneously in air at room temperature.
What kind of chemical properties does neptunium have?
Neptunium is a ductile, silvery, radioactive metal. Neptunium forms numerous chemical compounds. Chemically it is extremely reactive and is attacked by oxygen, steam and acids, but not by alkalis. It can exist in many oxidation states, from neptunium (II) to neptunium (VII).
How is neptunium used in the real world?
Neptunium, being a synthetic radioactive element, has no commercial uses at present but it is used to synthesize other elements such as plutonium – 238 etc. It is used as a precursor in plutonium – 238 production. Neptune – 237 is irradiated with neutrons to produce 238Pu. Reaction is given below –
Is there radioactive neptunium in Your House?
There may be radioactive neptunium in your house! Neptunium accumulates in a common household item: ionizing smoke detectors. To detect smoke, another actinide element, americium-241, emits radiation and turns into neptunium-237.
