Identify the incorrect statement regarding a crystal showing Schottky defect?

Options

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

Explanation

To identify the incorrect statement regarding a crystal showing Schottky defect, we will analyze the properties and characteristics of Schottky defects in ionic crystals step by step.

### Step-by-Step Solution:

1. **Understanding Schottky Defect**:
- A Schottky defect occurs in ionic crystals when an equal number of cations (A⁺) and anions (B⁻) are missing from the lattice. This results in vacancies in the crystal structure.

**Hint**: Remember that Schottky defects involve missing ions that maintain charge neutrality.
