Two nuclei having the same mass number are known as isobars. (a) Calculate the difference in binding energy per nucleon for the isobars 1123Na and 1223 Mg. (b) How do you account for this difference? (The mass of 1223Mg =22.994 127u)

If an atoms with 62 protons undergoes β-decay, the daughter nuclide will have ____ protons.\

Calculate the binding energy per mole of nucleons for sodium-23. Masses needed for this calculation are (in g/mol) H = 1.00783, n = 1.00867, and Na = 22.98977. (Na) = n kJ/mol nucleons

A plot of binding energy per nucleon versus the mass number (A) shows that nuclei with a small mass number have А a small binding energy per nucleon, as the mass number increases the binding energy per nucleon increases, and the value for the binding energy per nucleon has a maximum value for nuclei with a mass number around 60. Verify that this is the case by determining the binding energy per nucleon for each of the following four nuclei. (Let the mass of a proton be 1.0078 u, the mass of a neutron be 1.0087 u, the mass of 'He be 3.0160 u, the mass of Li be 8.0225 u, the mass of 2Ni be 61.9283 u, and the mass of 112, Cd be 111.9028 u.

Determine the energy released when a Uranium-235 nucleus under fission to Te-134, Zr-99, and two neurons. A table of isotopes lists the binding energy per nucleon on the nuclei of U-235, Te-134, and Zr-99 as 7.69 MeV, 8.38MeV, and 8.54MeV, respectively.

In the figure below, note that for low Z, all the nucleii with the most highest binding energy per nucleon have both an even number of protons and an even number of neutrons.
