LiF is a/an-

Options

A. Ionic crystal
B. Metallic crystal
C. Covalent crystal
D. Molecular crystal

Answer

To determine the type of crystal that Lithium Fluoride (LiF) is, we need to analyze its structure and bonding characteristics.

### Step-by-Step Solution:

1. **Identify the Composition of LiF**:
- Lithium Fluoride (LiF) is composed of lithium ions (Li⁺) and fluoride ions (F⁻).

2. **Understand Ionic Bonds**:
- Ionic crystals are formed when there are oppositely charged ions that are held together by electrostatic forces of attraction. This occurs between a metal and a non-metal.

3. **Classify the Type of Crystal**:
- In the case of LiF, lithium (Li) is a metal and fluoride (F) is a non-metal. The lithium ion (Li⁺) has a positive charge, while the fluoride ion (F⁻) has a negative charge.

4. **Confirm the Nature of the Bonding**:
- The lithium ions and fluoride ions are attracted to each other due to their opposite charges, which is characteristic of ionic bonding.

5. **Conclusion**:
- Since LiF is made up of ions that are held together by electrostatic forces of attraction, it is classified as an ionic crystal.

### Final Answer:
LiF is an ionic crystal.
