(c) Frenkel defect
(d) Frenkel and Schottky defects

Answer 1

Explanation:

Crystal defect indicated in the diagram below is(d) Frenkel and Schottky defects

Answer 2

This is a shottky defect.

Explanation:

• A defect in a crystal structure is defined as the absence of one or more ions from its position where it should be present, but isn't.

• Shottky defect is defined as missing of equivalent amounts of cations and anions which keep the charge of the crystal to neutral, but there becomes free spaces in the lattice where the ions are absent.

• This decreases the density of the crystal.

• Here in the crystal structure we can see that in this part of crystal, 2 sodium cation and 2 chloride anions are missing.

• This is actually missing of equivalent amounts of ions from lattice.

• So its a shottky defect.
