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).

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 required to produce this condition is called “critical mass”...
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 ...
A hydrogen-1 atom has a mass of 1.007 u (or Da or amu). A carbon-12 atom is defined as having a mass of 12 u. The largest known protein, titin, has a mass of 3 x 106Da. AMU is used to differentiate between isotopes. An atom of U-235, for example, has a lower AMU than ...

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. ...

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. ...
Atomic bombs have been designed by students, but their actual construction is a complex industrial process. Practical fissionable nuclei for atomic bombs are the isotopes uranium-235 and plutonium-239, which are capable of undergoingchain reaction. If the mass of the fissionable material exceeds the...
Rick Robinson's First Law of Space Combat: An object impacting at 3 km/sec delivers kinetic energy equal to its mass in TNT. This means a stupid boulder traveling at 2,000 kilometers per second will inflict the damage of 400 kilotons of TNT per ton of rock. Which means each ton of ...
