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,Na^(+)):}`

A

Frenkle defect

B

Schottky defect

C

Interstitial defect

D

Frenkle defect and Schottky defect

Text Solution

Verified by Experts

The correct Answer is:
B
Equal no , of `Na^(+) `and `CI^(-)` is missing completely
`rArr ` schattky defect.
