Which of the effects listed below is not a major effect influencing the binding energy of the nucleus in the liquid-drop model?
A) The volume effect: the binding energy per nucleon is approximately constant when A 50.
B) The surface effect: nucleons in the surface have fewer neighbors.
C) The quantum number effect: all nucleons in the nucleus have the same set of quantum numbers.
D) The Coulomb repulsion effect: protons repel protons.
E) The symmetry effect: stable nuclei tend to have N ≈ Z.

Quizplus · Accepted Answer

The quantum number effect does not significantly affect the binding energy of the nucleus in the liquid-drop model because all nucleons in the nucleus have the same set of quantum numbers regardless of their position or number. The other effects listed (volume, surface, Coulomb repulsion, and symmetry effects) are major factors that influence the binding energy of the nucleus.
