Question

Which of the following assumption of Quantum Free Electron Theory is modified in
Kronig - Penny Model?
(a) The energy values of the conduction electrons are quantized.
(b) The filling up of electrons in various allowed energy levels takes place according
to Pauli's exclusion principle.
(c) The electrons travel under a constant potential inside the metal but cannot go
outside the boundary of lattice.
(d) Distributions of electrons in various energy levels take place according to Fermi
Dirac statistics and not by Maxwell-Boltzmann statistics.​
