Draw energy-level diagrams, for all A = 14 nuclei listed in Appendix D. Show all

Question

Draw energy-level diagrams, for all A = 14 nuclei listed in Appendix D. Show all the occupied neutron and proton levels. Given the diagrams, are any of the nuclei obviously unstable?

The only nuclei with A = 14 is Carbon 14 with an atomic mass of 14.003242 u and a half life of 5730 yrs.

Explanation / Answer

Some info is missing like the Appendix D. By the way, it depends, generally speaking, by the level of isotopy. An isotope of an element has the same number of electrons and different numbers of neutrons. The largest it is, the more instable the nucleus is because the range of the nuclear binding forces is quite small, and if the nucleus gets fatter and fatter because it is too rich in neutrons, its size can surpass the binding energy range.
