What is the main use of neptunium?
The main use of neptunium-237 is in devices for detecting high-energy neutrons. Neptunium is dangerous. As well as radioactive, it’s also pyrophoric, capable of spontaneously catching fire at room temperature. Neptunium was discovered in 1940 by Edwin McMillan and Philip H.
Why is neptunium not used?
There are several reasons that neptunium may not be used. The first is the abundance of neptunium. From Wikipedia, it states the best source is from spent fuel rods. Basically, someone would need to handle very radioactive material to obtain a small amount of neptunium.
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.
What is neptunium melting point?
1,191°F (644°C)
Neptunium/Melting point
How does neptunium decay to plutonium?
Neptunium-238 has a half-life of 2.1 days and decays into plutonium-238 through beta decay. It decays into uranium-240 through alpha decay. Plutonium-244 will also decay through spontaneous fission. Only two of plutonium’s isotopes, plutonium-238 and plutonium-239, have found uses outside of basic research.
What is neptunium atomic mass?
237.0482 u
Neptunium/Atomic mass
How is neptunium similar to plutonium?
Neptunium reacts with hydrogen in a similar manner to its neighbor plutonium, forming the hydrides NpH 2+x (face-centered cubic) and NpH 3 . These are isostructural with the corresponding plutonium hydrides, although unlike PuH 2+ x , the lattice parameters of NpH 2+ x become greater as the hydrogen content ( x ) increases.
What does the name neptunium mean?
• NEPTUNIUM (noun) The noun NEPTUNIUM has 1 sense: 1. a radioactive transuranic metallic element; found in trace amounts in uranium ores; a by-product of the production of plutonium. Familiarity information: NEPTUNIUM used as a noun is very rare. Dictionary entry details. • NEPTUNIUM (noun)
What is the origin name for neptunium?
Origin of name : named after ” the planet Neptune “. Neptunium was the first synthetic transuranium element of the actinide series. It was discovered by McMillan and Abelson in 1940 at Berkeley, California, USA, who bombarded uranium with neutrons produced from a cyclotron.
How was neptunium formed?
Neptunium is not found in pure elemental form in nature as it is a synthetic element and forms by nuclear reaction of uranium . It generally forms a green coating of its oxide when exposed to moist air. It is a hard, ductile, radioactive and silvery colored actinide metal.
