What type of crystal defect is indicated...

What type of crystal defect is indicated in the diagram given below :
`{:(Na^(+),Cl^(-),Na^(+),Cl^(-),Na^(+),Cl^(-)),(Cl^(-),square,Cl^(-),Na^(+),square,Cl^(-)),(Na^(+),Cl^(-),square,Cl^(-),Na^(+),Cl^(-)),(Cl^(-),Na^(+),Cl^(-),Na^(+),square,N^(+)):}`

A

Frenkel and Schottky defects

B

Schottky defect

C

Interstitial defect

D

Frenkel defect

Text Solution

Verified by Experts

The correct Answer is:
B
These defect are produced when one `.^(+)ve` and one `-` ve ion are missing from their respective positions removed.
