Question

Which theory is useful in explaining electrical conductivity in conductors and semiconductors?Select the proper choice from the given multiple choices.(A) Pauli’s principle (B) Avogadro’s theory(C) Band theory (D) Hybridisation theory

Answer 1

D) Hybridisation theory

Answer 2

Answer:

(C) Band theory

Explanation:

Band theory is useful in explaining electrical conductivity in conductors and semiconductors.

Band theory, depicts the state of electrons in solid components that can have energy values only within certain particular ranges. An electron's behaviour in a solid is associated with the behaviour of all other particles around it.

In conductors and semiconductors because of dividing one or more atomic energy levels, each band is created. The minimum amount of states in a band is therefore twice the amount of atoms in the material. The reason for the two factor is that each energy level can contain two opposite-spin electrons.
