Which of the following is a non-stoichiometric defect?
(a)Frenkel defect
(b)Schottky defect
(c)metal deficiency defect
(d)interstitial defect
(c)metal deficiency defect
Explanation:
In Frenkel defects the smaller ion occupies the interstitial sites and in Schottky defects the same number of cations and anions are missing. Intermittent defects occupy sites of an atom or molecule enthalpy, so these three defects do not disturb the ratio of positive and negative ions (stoichiometric) of a solid.
