The Fermi energy of a metal depends primarily on:
A)the temperature
B)the volume of the sample
C)the mass density of the metal
D)the size of the sample
E)the number density of conduction electrons

Question

Quizplus · Accepted Answer

The Fermi energy of a metal primarily depends on the number density of conduction electrons. This is because the Fermi energy is the energy level at which electrons have a 50% probability of being filled at absolute zero, and the number density of conduction electrons determines the number of available energy states at that energy level.
