A. zero and half integer

B. half integer and zero

C. an integer and half integer

A. The nuclear force between neutrons is stronger than that between protons

B. The nuclear force between protons is of a shorter range than those between neutrons, so that a smaller number of protons are held together by the nuclear force

C. Protons are unstable, so their number in a nucleus diminishes

D. It costs more energy to add a proton to a (heavy) nucleus than a neutron because of the Coulomb repulsion between protons
