At low atomic numbers, stable atomic nuclei have roughly equal numbers of protons and neutrons (a ratio of 1:1). How does the neutron/proton ratio change for stable nuclei as the atomic number increases? What is the approximate n:p ratio for elements near the end of the Periodic Table (atomic numbers above 80)?

A pair of nuclei for which Z1 = N2 and Z2 = N1 are called mirror isobars (the atomic and neutron numbers are interchanged). Binding-energy measurements on these nuclei can be used to obtain evidence of the charge independence of nuclear forces (that is, proton-proton, proton-neutron, and neutron-neutron nuclear forces are equal). Calculate the difference in binding energy for the two 15 ror isobars s ic masses as necessary.) and 7·The electric repulsion among eight protons rather than seven accounts...
