ZnS sulphide is an example of

Options

A. Ionic crystal
B. Covalent cyrstal
C. Metallic crystal
D. Van der Waal crystal

Answer

To determine the type of crystal structure that ZnS (zinc sulfide) represents, we can follow these steps:

### Step 1: Identify the Composition of ZnS
ZnS is composed of zinc (Zn) and sulfur (S). Zinc is a metal, while sulfur is a non-metal.

**Hint:** Look at the elements that make up the compound to determine the type of bonding.

### Step 2: Determine the Type of Bonding
In ZnS, zinc loses two electrons to form a Zn²⁺ ion, and sulfur gains two electrons to form an S²⁻ ion. The electrostatic attraction between these oppositely charged ions indicates that the bonding is ionic.

**Hint:** Consider the charge of the ions formed from the elements in the compound.

### Step 3: Classify the Crystal Type
Since ZnS is formed through ionic bonding, it is classified as an ionic crystal. Ionic crystals are characterized by a regular arrangement of ions held together by strong electrostatic forces.

**Hint:** Recall the characteristics of different types of crystals (ionic, covalent, metallic, and Van der Waals) to make the classification.

### Step 4: Conclusion
Based on the analysis, ZnS is an example of an ionic crystal.

**Final Answer:** ZnS is an example of an ionic crystal.
