The crystal with metal deficiency defect...

The crystal with metal deficiency defect is:

A

NaCl

B

FeO

C

KCl

D

ZnO

Text Solution

Verified by Experts

The correct Answer is:
B
In FeO, as some Fe may be present as `Fe^(3+)` and for charge neutrality `3 Fe^(2+) = 2Fe^(3+)` . Hence, FeO should have metal deficiency defect

Which solid shows metal deficiency defect?

Which of the following set of compounds will show metal deficiency defect?

In an ideal crystal, the entropy of the constituents at absolute zero temperature (0K) is zero. However, the crystals generally suffer from certain defects also called imperfections They may be both electronic and atomic in nature. The atomic imperfections may be stoichiometric (Schottky and Frenkel defects) or non-stoichiometric (metal excees and metal deficiency defects). In addition to these, there are impurity defects which are caused by the addition of certain impurities of metals and this is known as dopping. The dopping leads to semi conductors which may be either n-type or p-type in nature. In stoichiometric defects, the ratio of positive and negative ions as indicated by chemical formula of the compound:
