Schottky defect in a crystal is observed when

A

an ion leaves its normal site and occupies an interstitial site

B

unequal number of cations and anions are missing from the lattice

C

density of the crystal is increased

D

equal number of cations and anions are missing from the lattice

Text Solution

Verified by Experts

The correct Answer is:
D
Schottky defect in crystals is observed when equal number of cations and anions are missing from the lattice. So, the cytstal remains neutral, e.g. NaCl.
