Solid State Question 25
Question: Crystal defect indicated m the diagram below is
$ N{{a}^{+}}C{{l}^{-}}N{{a}^{+}}C{{l}^{-}}N{{a}^{+}}C{{l}^{-}} $ $ C{{l}^{-}}[]C{{l}^{-}}N{{a}^{+}}[]N{{a}^{+}} $ $ N{{a}^{+}}C{{l}^{-}}[]C{{l}^{-}}N{{a}^{+}}C{{l}^{-}} $ $ C{{l}^{-}}N{{a}^{+}}C{{l}^{-}}N{{a}^{+}}[]N{{a}^{+}} $
Options:
A) Interstitial defect
B) Schottky defect
C) Frenkel defect
D) Frenkel and Schottky defects
Show Answer
Answer:
Correct Answer: B
Solution:
[b] When equal number of cations $ (N{{a}^{+}}) $ and anions $ ( C{{l}^{-}} ) $ are missing from their regular lattice positions, we have schottky defect.
