Neptunium is a synthetic chemical element with the atomic number 93 and the symbol Np. It is a radioactive metal that is part of the actinide series, which includes elements with atomic numbers 89 through 103. Neptunium was discovered in 1940 by a team of scientists led by Edwin McMillan and Philip Abelson at the Berkeley Radiation Laboratory in California.
The most stable isotope of neptunium is neptunium-237, which has a half-life of approximately 2.14 million years. It is produced through the bombardment of uranium-238 with neutrons in a nuclear reactor or through the decay of plutonium-239. Neptunium has several uses in the nuclear industry, including as a neutron source and as a component in some types of nuclear fuel.
In addition to its use in the nuclear industry, neptunium has also been explored for potential use in medicine. Some studies have suggested that it could be used in the treatment of certain types of cancer, although more research is needed to fully understand the potential risks and benefits of this use.
Despite its potential uses, neptunium is considered a hazardous substance due to its radioactivity. It can be harmful to humans if ingested or inhaled, and precautions must be taken to protect against exposure. As with all radioactive materials, the handling and disposal of neptunium must be done with care to minimize the risk of radiation exposure.
In summary, neptunium is a radioactive metal with a variety of uses in the nuclear industry. It has the potential to be used in medicine, although more research is needed to fully understand its risks and benefits. As a hazardous substance, neptunium must be handled and disposed of with care to protect against radiation exposure.

Electron affinities are more difficult to measure than ionization energies. What is it used for? See also: Density of Neptunium Density of Neptunium is 20. The isotopic mass usually differs for other isotopes and is usually within 0. Another way to read periodic table and locate an element is by using group number column and period number row. Refer to below table for Neptunium Physical Properties 20.
The boiling point of neptunium is not empirically known and the usually given value of 4174 °C is extrapolated from the vapor pressure of the element. Copyright of and ownership in the Images reside with Murray Robertson. The electronic configuration of Neptunium will be 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p6 4f14 5d10 6s2 6p6 5f4 6d1 7s2. 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. Fermi had in fact discovered nuclear fission but not realised it. Natural abundance Where the element is most commonly found in nature, and how it is sourced commercially. Boiling Point of Neptunium in Kelvin is 4273 K.
What is the classification of neptunium? Neptunium, symbol Np, has a Simple Orthorhombic structure and Silver color. Neptunium isotopes are found naturally in uranium ores which are formed as decay products from the transmutation reactions. Emission of gamma ray results in beta decay which in turn increases the atomic number of the resulting isotope. The group 13 elements consist of six elements. Chemical Characteristics Neptunium is a very reactive metal. To locate Neptunium on periodic table look for cross section of group- and period 7 in the modern periodic table.
The boron group are the chemical elements in group 13 of the periodic table, comprising boron B , aluminium Al , gallium Ga , indium In , thallium Tl , and perhaps also the chemically uncharacterized nihonium Nh. Mary McMahon Ever since she began contributing to the site several years ago, Mary has embraced the exciting challenge of being a AllTheScience researcher and writer. It is the densest of the actinides and can remain a liquid for the largest temperature range of any known element. Neptunium, successor of uranium, was discovered in 1940 by Edwin McMillan and Philip H. Neptunium accumulates in a common household item: ionizing smoke detectors. Neptunium ions in aqueous solution possess characteristic colours: Np 3+, pale purple; Np 4+, pale yellow-green; NpO 2 +, green-blue; NpO 2 2+, varying from colourless to pink or yellow-green, depending on the anion present; and Np 7+, dark green.
Np Neptunium Element Information: Facts, Properties, Trends, Uses and comparison
For 63Cu, the atomic mass is less than 63, so this must be the dominant factor. Currently, neptunium does not have any commercial use. But at least neptunium fans can say that it has a name that trumps even New York. It occurs in traces and does not have any biological role. The most stable state in solid form is +4 while +5 valence state is preferred in solution form. What is the characteristics of neptunium? However, more energy is required to add an electron to a negative ion which overwhelms any release of energy from the electron attachment process. Isotopes Atoms of the same element with different numbers of neutrons.
Abelson while they were trying to isolate fission products. It is represented by the symbol Np and has atomic number 93. Neptunium, a silvery metal, exists in three crystalline modifications; the room-temperature form alpha is orthorhombic. It is used in plutonium production which in turn has uses in military and is also used as fuel to provide electricity to space craft. The chemical symbol for Neptunium is Np. Sublimation The transition of a substance directly from the solid to the gas phase without passing through a liquid phase. Neptunium is a byproduct of nuclear reactor operations and has also been produced in small quantities through the bombardment of uranium and plutonium with neutrons.

Glossary Atomic radius, non-bonded Half of the distance between two unbonded atoms of the same element when the electrostatic forces are balanced. What is the position of Neptunium in the Periodic Table? Like uranium, plutonium can also be used to fuel nuclear power plants. Electronegativity Electronegativity, symbol χ, is a chemical property that describes the tendency of an atom to attract electrons towards this atom.
In 1934, Odolen Koblic claimed to have extracted a small amount of element 93 from pitchblende but when analysed it turned out to be a mixture of two other metals. Lees ook: Hoe fluit je beter? Who proved that an element having the atomic number 93 could be created? In practice there is very little use for neptunium. Fermi published his finding of element 93 but several objections were raised against his claims. This undergoes the nuclear reaction called beta decay, where a neutron turns into a proton, giving off an electron in the process for historical reasons, the electron is called a beta particle in such circumstances. It is part of group null. Abelson in year 1940 in United States. Latent Heat of Fusion of Neptunium is 5.
