A) the maximum energy electrons can have in a metal at T = 0 K.
B) the maximum energy electrons can have in a metal at T = 0 C.
C) the minimum energy electrons can have in a metal at T = 0 K.
D) the number of electrons per unit volume between E and E + dE.
E) the minimum energy electrons can have in a metal at T = 0 C.

Question

Quizplus · Accepted Answer

The Fermi energy is the energy level at which the highest-energy electrons in a metal occupy at absolute zero temperature. At this temperature, all the lower energy levels are fully occupied by electrons, and the Fermi energy represents the maximum energy that electrons in the metal can have. Therefore, choice A is the correct answer.

The Fermi Energy Corresponds to
