A parameter labeled n is called the repulsion parameter. It appears in the potential energy term describing the repulsion between nearest neighbor ions. How is n described by the book to be determined for a particular pair of ions? It's determined experimentally. O It's determined by Coulomb's Law. O It's determined by Pauli Exclusion Principle.
