Question

The manifestation of band structure in solids is due to

• A. Heisenberg uncertainty principle
• B. Pauli’s exclusion principle
• C. Bohr’s correspondence principle
• D. Boltzmann law

Answer 1

Answer: (B)

Pauli’s exclusion principle

Answer 2

: According to the Pauli’s exclusion principle, the electronic configuration of number of subshells existing in a shell and number of electrons entering each sub shell is found.

Hence, on the basis of the Pauli’s exclusion principle, manifestation of band structure in solids can be explained.
