Q12 / 160 · AP EAMCET 2020 (17 Sep Shift 2) · Chemistry

The defect produced due to the presence of extra cations at interstitial sites is called

Correct answer
A
metal excess defect
B
Schottky defect
C
metal deficiency defect
D
Frenkel defect

Solution

When a metal contains extra cations (metal ion) in the interstitial site of its lattice. We observe metal excess defect. It is a non-stoichiometric defect.

Hence, the correct answer is option: 'A'.
