Atomic mass unit ( amu ) Atomic mass unit: Abbreviated as “ amu .” A mass equal to one twelfth the mass of an atom of carbon-12. amu to kg. 1 amu = 1.66053873 x 10 -27 kilogram. 1 amu = 1.66053873 x 10-24 gram. Table of critical energies and binding energies of radioactive fuels:, Nuclear Binding Energy and the Mass Defect . A neutron has a slightly larger mass than the proton. These are often given in terms of an atomic mass unit, where one atomic mass unit (u) is defined as 1/12th the mass of a carbon-12 atom.
Mass defect (also called mass deficit) is the difference between the mass of an object and the sum of the masses of its constituent particles. Discovered by Albert Einstein in 1905, it can be explained using his formula E = mc 2 , which describes the equivalence of energy and mass .
3. Atomic mass unit ( amu ) One amu is equal to (left(frac{1}{12}right)) of the mass of one atom of 6 C 12. 1 amu = 1u = 1.66 × 10-27 kg Energy of 1 amu = 931.5 MeV. 4. Mass defect and nuclear binding energy. In reality the mass of the nucleus is always less than the total mass of its components. The difference is called mass defect .
Binding Energy = mass defect x c 2. where c= speed of light in vacuum. c = 2.9979 x 10 8 m/s. Solved Examples. Problem 1: Calculate the binding energy per nucleon for an alpha particle whose mass defect is calculated as 0.0292amu. Given: mass defect = 0.0292amu. Convert the mass defect into kg (1 amu = 1.6606 x 10-27 kg), Nuclear Binding Energy and the Mass Defect, Binding Energy Formula And Mass Defect – Solved Examples, Nuclear Binding Energy and the Mass Defect, Binding Energy Formula And Mass Defect – Solved Examples, Calculation of Binding Energy—Since the mass defect was converted to BE (binding energy) when the nucleus was formed, it is possible to calculate the BE using a conversion factor derived by the mass –energy relationship from Einstein’s Theory of Relativity.Einstein’s famous equation relating mass and energy is E=mc 2 where c is the velocity of light (c=2.998×108 m/sec).
