It provides atomic mass, mass excess, nuclear binding energy, nucleon separation energies, Q-values, and nucleon residual interaction parameters for atomic nuclei of the isotope U-238 (Uranium, atomic number Z = 92, mass number A = 238)....
isotopes of an element, all of which have the same atomic number (number of protons) and are represented by the same literal symbol; for example, the two best known isotopes of uranium (those with mass numbers 235 and 238) are designated uranium-235 (symbolized 235U) and uranium-238 (...
An atom of uranium-235 (U-235) has an AMU of approximately 235. However, an atom of uranium-238 (U-238) is slightly more massive and thus has a larger mass. Its AMU is 238. The AMU difference occurs because U-238, which is the most abundant naturally occurring uranium isotope, has...
Nuclear fissionThe impact of a slow (low-energy) neutron splitting the nucleus of the uranium isotope U-235 into two new nuclei. These can be nuclei of any of 30 or more elements ranging in atomic number from 30 to 64. Krypton and barium are examples. Energy and neutrons (2 or 3 for...

The sum of theatomic massof the two atoms produced by the fission of onefissileatomis always less than the atomic mass of the original atom. This is because some of the mass is lost as freeneutrons, and once kinetic energy of the fission products has been removed (i.e., the products ...
U-235 and U-238 absorb slow neutrons, the probability of fission in U-235 is much greater than in U-238. The U-238 is more likely to form a new isotope U-239, and this isotope rapidly emits an electron to become a new element with a mass of 239 and an Atomic Number of 93. ...
atomic mass, atomic weight mass - the property of a body that causes it to have weight in a gravitational field combining weight, eq, equivalent weight, equivalent - the atomic weight of an element that has the same combining capacity as a given weight of another element; the standard is ...
Homework--- Build Atomic Bomb What is the general output of enriched uranium from an electrolysis and fractional distillation process? I have already researched the outputs for gas diffusion, thermal diffusion, gas cenrifuge, laster isotope separation, and mass spectroscopy. If you could give... ...
What is the change in atomic mass number when an atom emits an alpha particle? What is the equation for beta minus decay? Is alpha decay ionizing? What happens in beta plus decay? What happens during beta decay? U-238 decomposes into Pb-206 by a series of decays. These include ___ ...
