Chemistry Question on The solid state
Schottky defect in crystals 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 crystal lattice
C
equal number of cations and anions are missing from the crystal lattice
D
there is large difference in size of positive and negative ions.
Answer
equal number of cations and anions are missing from the crystal lattice
Explanation
Solution
In order to maintain electrical neutrality, the number of missing cations and anions are equal in Schottky defect
