Chemistry Question on The solid state

Which of the following represents correct order of conductivity in solids?

A

Kmetals>>Kinsulators<KsemiconductorK_{\text{metals}} >> K_{\text{insulators}} < K_{\text{semiconductor}}

B

Kmetals<<Kinsulators<KsemiconductorK_{\text{metals}} << K_{\text{insulators}} < K_{\text{semiconductor}}

C

Kmetals<Ksemiconductor>KinsulatorsK_{\text{metals}} < K_{\text{semiconductor}} > K_{\text{insulators}}

D

Kmetals<Ksemiconductor>KinsulatorsK_{\text{metals}} < K_{\text{semiconductor}} > K_{\text{insulators}}

Answer

Kmetals>>Kinsulators<KsemiconductorK_{\text{metals}} >> K_{\text{insulators}} < K_{\text{semiconductor}}

Explanation

Solution

Conductivity of metal, insulator and semiconductors can be represented in the term of kk (Kappa) which depends upon energy gap between valence band and conduction band. Hence, correct order is kmetal>>kinsulators<ksemiconductorsk_{\text{metal}} > > k_{\text{insulators}} < k_{\text{semiconductors}}
