Which of the following is NOT a true statement about the relationship between the thermal expansion of a solid and the potential energy of an ion in a solid?

a. The potential energy curve for an ion in a solid is not symmetric about the minimum energy point. b. The ions within the solid both attract and repel other ions in the solid. c. As the temperature increases from zero, ions begin to oscillate with potential energy like that of a simple-harmonic oscillator. d. The Pauli exclusion principle provides some repulsion for electron shell overlap.
