The crystal lattice of electro covalent compounds is composed of

Options

A. Option 1. Atoms
B. Option 2. Molecules
C. Option 3. Oppositely charged ions
D. Option 4. Both molecules and ions

Answer

To answer the question regarding the composition of the crystal lattice of electro covalent compounds, we will analyze the structure of an ionic compound, specifically sodium chloride (NaCl), as an example.

### Step-by-Step Solution:

1. **Understanding Ionic Compounds**:
- Ionic compounds are formed by the electrostatic attraction between positively charged ions (cations) and negatively charged ions (anions).

2. **Example of Sodium Chloride (NaCl)**:
- Sodium chloride (NaCl) is a classic example of an ionic compound. In this compound, sodium (Na) acts as the cation and chloride (Cl) acts as the anion.

3. **Crystal Lattice Structure**:
- The crystal lattice of NaCl can be visualized as a three-dimensional arrangement where each sodium ion is surrounded by six chloride ions and vice versa.
- This arrangement creates a repeating pattern that extends throughout the crystal.

4. **Drawing the Lattice**:
- If we were to draw the crystal lattice, we would see that the chloride ions occupy the corners of the cube, while the sodium ions are located at the center of the cube and the face centers.

5. **Charge Distribution**:
- In the lattice structure, the sodium ions (Na⁺) are positively charged, while the chloride ions (Cl⁻) are negatively charged. This arrangement of oppositely charged ions is crucial for the stability of the lattice.

6. **Conclusion**:
- Therefore, the crystal lattice of electro covalent compounds, specifically ionic compounds like NaCl, is composed of oppositely charged ions.

### Final Answer:
The crystal lattice of electro covalent compounds is composed of **oppositely charged ions**.
