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 Pu-235 (Plutonium, atomic number Z = 94, mass number A = 235).

Chlorine, for example, has an atomic mass value of 35.453 u, while copper has one of 63.54 u. These values of the atomic masses can be explained by the effect of the relative abundances of the isotopes of the elements contributing to produce the observed net mass. If an element consists ...
Each element in theperiodic tableconsists of atoms, and each atom has a unique atomic mass and unique atomic number. The atomic number refers to the number of protons in the atom's nucleus, while atomic mass reflects the sum of the number of protons and neutrons. It is expressed in AMU ...
It was the first fissile Uranium isotope to be discovered. When one neutron from the U-235 fission reaction causes another nucleus of this metal to undergo fission, it causes the entire chain reaction to continue. This condition is called the “critical condition” while the mass of U-235 re...
An atom may be conveniently symbolized by its chemical symbol with the atomic number and mass number written as subscript and superscript, respectively. For example, the symbol for uranium is U (atomic number 92); the isotopes of uranium with atomic weights 235 and 238 are indicated by 23592U...
The minimum amount to start a chain reaction as described above is known as supercritical mass. For pure U-235, it is 110 pounds (50 kilograms). No uranium is ever quite pure, however, so in reality more will be needed, such as U-235, U-238, and Plutonium. ...
Fission product yields by mass forthermal neutronfission ofuranium-235,plutonium-239, a combination of the two typical of current nuclear power reactors, anduranium-233used in thethorium cycle. Each fission of a parent atom produces a different set of fission product atoms. However, while an ind...

1.a bomb whose potency is derived from nuclear fission of atoms of fissionable material with the consequent conversion of part of their mass into energy. 2.a bomb whose explosive force comes from a chain reaction based on nuclear fission in U-235 or plutonium. ...
