Identify the incorrect statement regarding a crystal showing Schottky defect?

Options

A. (a) Entropy of the crystal increases
B. (b) The density of the overall crystal decreases
C. (c) The cation are missing at some lattice points and occupy intertitial sites
D. (d) Electrical neutrality of the crystal is maintained

Explanation

When equal number of cations and anions are missing from their position in a crystal lattice so that electrical neutrality is maintained, the defect is called Schottky defect. Due to missing of ions, the overall density of the crystal decreases. Moreover, defect leads to randomness, thus entropy also increases.
