Appearance and Characteristics

Neptunium is sandwiched on the periodic table between uranium and plutonium, which are also radioactive. All three of these elements, named after planets, have between 92 and 94 protons in their nuclei, large enough to undergo a nuclear fission reaction, or "atom splitting." Due to this capability, uranium and plutonium are both widely used in nuclear power plants and weapons. Neptunium, however, was discovered significantly later in history than either of its periodic table neighbors, and is not widely used. 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. Understanding neptunium's chemistry is essential to ensure safe long-term nuclear waste storage.

Just four years later in 1938, Romanian physicist Horia Hulubei and French chemist Yvette Cauchois made a similar false report of discovering element 93. They claimed that they found the element in a naturally occurring mineral sample. At the time, scientists rejected this, believing no elements with more protons than uranium (transuranium elements) were present in nature.

Properties, sources and uses of the element neptunium

Like other actinides, neptunium readily forms a dioxide neptunyl core (NpO2). In the environment, this neptunyl core readily complexes with carbonate as well as other oxygen-containing ionic groups, such as OH-, NO2-, NO3-, and SO42-). In so doing, it forms charged complexes that tend to be readily mobile with low affinities to the soil. Examples of these complexes are: Source: Miniscule concentrations of neptunium-237 and neptunium-239 are found naturally in uranium ores.

McMillan and chemist Philip H. Abelson first found neptunium in 1940 after uranium had been bombarded by neutrons from the cyclotron at Berkeley, California. The element was named after the planet Neptune, which is the first planet beyond Uranus.

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. But no need to worry: the amount of radioactive material in smoke detectors is negligible and causes no harm to human health, according to Emsley. Smoke detectors contain less than 0.00000001 ounces (0.0000003 grams) of americium, which decays so slowly that only about 0.2 percent of this already small amount converts to neptunium each year.  translation and definition neptunium, English-Russian Dictionary online.

From Wikipedia, the free encyclopedia. Chemical element with atomic number 93 A longer lived isotope neptunium-237 was discovered in 1942. Scientists A. C. Wahl and Glenn T. Seaborg bombarded uranium-238 with fast neutrons in the Berkeley 60-inch cyclotron. They isolated several hundred milligrams of neptunium and made a thorough study of its properties. (1) Neptunium definition is - a radioactive metallic element that is chemically similar to uranium and is obtained in nuclear reactors especially as a by-product in the production of plutonium Scientists are, however, concerned with the long-term storage of neptunium present in spent nuclear fuel, according to a 2005 article published by Berkeley Lab. Although neptunium makes up only a small percentage of total radioactive waste, it poses a particular threat because it is long-lasting and hard to extract. Amy Hixon, an assistant professor at the Notre Dame College of Engineering, has studied the less familiar actinide elements and how to best contain them.

Neptunium-237 is produced in kilogram quantities from radioactive waste from power reactors Neptunium was named for the planet Neptune, the next planet out from Uranus, after which uranium was named. It was first discovered by Edwin McMillan and Philip H. Abelson in 1940. Initially predicted by Walter Russell's "spiral" organization of the periodic table, it was found at the Berkeley Radiation Laboratory of the University of California, Berkeley. The research team produced the neptunium isotope 239Np (2.4-day half-life) by bombarding uranium with slow-moving neutrons. It was the first transuranium element produced synthetically and the first actinide series transuranium element discovered. Neptunium is fissionable, and could theoretically be used as reactor fuel or to create a nuclear weapon. In 1992, the U.S. Department of Energy declassified the statement that Np-237 "can be used for a nuclear explosive device."[2] It is not believed that an actual weapon has ever been constructed using neptunium. The neptunium series is a radioactive series beginning with neptunium-237. Its members are produced artificially by nuclear reactions and do not occur naturally, because the half-life of the..

5 mind-boggling Moon mysteries that science cannot explain

According to John Emsley in his book, "Nature’s Building Blocks: An A-Z Guide to the Elements" (Oxford University Press, 1999), Italian scientist Enrico Fermi was the first to claim he discovered element 93, in 1934. He hypothesized that elements heavier than uranium (element 92) could be created by bombarding uranium with neutrons. Theoretically, this would add one neutral mass unit to the uranium atoms, which would then undergo beta decay, or loss of a negative charge that turns a neutron into a proton, resulting in an element with 93 total protons. Fermi's experiment did not end up producing an element; instead of the neutrons fusing with the uranium atoms, they split the uranium atoms into many fragment radioisotopes. Fermi was criticized for his false claim, and did not know at the time that he had actually performed the first atom splitting, or fission, experiment. Neptunium är en svensk importör som distribuerar kvalitetsöl från mikrobryggerier. Neptunium. Food and drinks company in Stockholm, Sweden Neptunium is found in nature only as trace amounts in Uranium ore as a product of neutron capture and beta decay of Uranium. No natural minerals contain significant neptunium Neptunium (chemical symbol Np, atomic number 93) is a silvery radioactive metallic element, belonging to the actinide series. It is the first transuranic element[1] and the first member of this group to be produced synthetically. Its most stable isotope, 237Np, is a byproduct of nuclear reactors and plutonium production. It is also found in trace amounts in uranium ores. It can be used as a component in neutron detection equipment, and could potentially be used as fuel for a nuclear reactor or to create a nuclear weapon. When an atom of 235U captures a neutron, it is converted to an excited state of 236U. About 81 percent of the excited 236U nuclei undergo fission, but the remainder decay to the ground state of 236U by emitting gamma radiation. Further neutron capture creates 237U which has a half-life of seven days and thus quickly decays to 237Np. 237U is also produced via an n,2n reaction with 238U. Since nearly all neptunium is produced in this way or consists of isotopes which decay quickly, one gets nearly pure 237Np by chemical separation of neptunium.

Need the translation of Neptunium in English but even don't know the meaning? neptunium translated to English. TRANSLATION Neptunium is a silver metal and is very reactive, with four different oxidation states. When it combines with other elements it occurs as different colored solutions (purple, yellow, green and pink). Even on its own, neptunium occurs as three different allotropes, or physical forms, depending on the temperature. It is the densest of the actinides and can remain a liquid for the largest temperature range of any known element.

Element 93 was accepted as an existing element in 1940 at the University of California, Berkeley. Professor Edwin McMillan and graduate student Philip Abelson used a technique similar to Fermi, but with one important difference: they used slow-moving neutrons. McMillan used a machine called a cyclotron to slow the neutrons and then directed them at a uranium-238 target. This time, the neutrons actually worked to create element 93 by fusing with the uranium atoms instead of breaking them apart. Abelson analyzed the resulting sample, and noted unusual beta radiation that showed a new isotope (later named Np-289) was present. McMillan and Abelson decided to call the element neptunium because Neptune is the next planet beyond Uranus in the solar system. The discovery was the first transuranium element to be synthesized in a lab and earned McMillan a Nobel Prize in 1951. Letzter Beitrag von Neptunium in Re: Neues ASUS TUF A15, am Gestern um 15:30:29.

Neptunium is a chemical element with the symbol Np and atomic number 93. A radioactive actinide metal, neptunium is the first transuranic element Many neptunium radioisotopes have been characterized. The most stable of these are 237Np, with a half-life (t½) of 2.14 million years; 236Np, with a half-life of 154,000 years; and 235Np, with a half-life of 396.1 days. All the remaining radioactive isotopes have half-lives that are less than 4.5 days, and the majority of these have half-lives that are less than 50 minutes. This element also has four meta states, with the most stable being 236mNp (t½ 22.5 hours).

Neptunium forms tri- and tetrahalides such as NpF3, NpF4, NpCl4, NpBr3, and NpI3. It also forms oxides of various compositions, such as are found in the uranium-oxygen system, including Np3O8 and NpO2. The majority of neptunium, however, is anthropogenic; that is, it is created as a byproduct of reactions in nuclear power plants. Scientists can extract neptunium from spent nuclear fuel in large quantities. Because of its long half-life of 2.14 million years, Np-237 is the most abundant isotope of neptunium created. Most other isotopes of neptunium have short half-lives and decay within days.Fermium – Flerovium – Fluorine – Francium – Gadolinium – Gallium – Germanium – Gold Previous (Neptune (mythology)).
