binding energy- the energy required to separate particles from a molecule or atom or nucleus; equals the mass defect separation energy energy,free energy- (physics) a thermodynamic quantity equivalent to the capacity of a physical system to do work; the units of energy are joules or ergs; "en...
A mass number is a total count of all the protons and neutrons in the nucleus of an atom. Protons are the positively charged particles in the nucleus while the neutrons have a neutral charge. Each particle has a mass count of one. ...
In the case of the fission of a nucleus, the reaction is begun by the absorption of a slow neutron. Each fission produces two or three fast neutrons. In order to sustain a chain reaction, a sample must be large enough to slow the neutrons so that one can be captured by another ...
What is the density of an object with a mass of 60, g and a volume of 25, cm^3. The density of a material that has a mass 0.60 kg and occupies a volume 95.78 m^3 is equal to? Suppose a marble with a radius of 1.1 cm has the density of a nucleus 2....
A BFree Proton verses Nucleus Proton rest mass The energy associated with the mass of a free proton in the center of momentum frame where the proton’s momentum is zero is 938.272 (with more decimals). What is the rest energy of a single proton inside a Uranium atom? (It could be any...
1/12 the mass of a neutral atom of12C, equal to 931.5MeV. Atomic number (Z) Integer equal to the number of protons in a nucleus; the order of an element in the periodic table. Atomic weight or nuclear mass number (A) An integer equal to the sum of the number of protonsZand neutr...
If this occurs, we have a nuclear chain reaction. On the other hand, if too many neutrons escape the bulk material without interacting with a nucleus, then no chain reaction will occur.Material that can undergo fission as a result of any neutron bombardment is called fissionable; material ...

Numerical results are given for twenty mass divisions of 236U. Although it is found that the effect of non-axial deformations on the potential energy strongly depends on the mass asymmetry of the nucleus, a non-axial shape is energetically favoured in only one fission mode. Even in this case...
into huge amounts of energy and thus this mass is removed from the total mass of the original particles, and the mass is missing in the resulting nucleus.The nuclear binding energies are enormous, they are on the order of a million times greater than the electron binding energies of atoms....
