Question
This quantity is similar for mirror nuclei, for which the proton number of one equals the neutron number of the other, and vice versa. For 10 points each:
[10m] Name this quantity, the difference in energy between a nucleus and its individual nucleons considered collectively.
ANSWER: nuclear binding energy [accept nuclear mass defect or nuclear mass deficiency or nuclear mass deficit; prompt on E or delta-m]
[10e] The similarity of mirror nuclei binding energies is due to the charge independence of this fundamental force that holds nuclei together.
ANSWER: strong force [or strong nuclear force or strong interaction or residual strong force]
[10h] Pairs of mirror nuclei have this more general relationship in which two nuclei have equal numbers of nucleons. Lines with slope of negative one on a chart of nuclides describe this relationship that shares its name with a meteorological term.
