What type of crystal defect is indicated...

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

A

Both Frenkel and Schottky defects

B

Schottky defect

C

Interstitial defect

D

Frenkel defect

Text Solution

Verified by Experts

The correct Answer is:
B
Since equal number of cations (`2 Na^(o+)` ions) and anions (`2 Cl^(ɵ)` iions) are missing in the figure given, So it is Schottky defect.
