which of the following is a network solid?

Options

A. `SO_(2(Solid))`
B. `I_2`
C. Diamond
D. `H_2O_((Ice))`

Answer

To determine which of the following is a network solid, we will analyze each option based on the definition of network solids. Network solids are characterized by a continuous network of covalent bonds extending throughout the material, with no individual molecules present.

### Step-by-Step Solution:

1. **Understanding Network Solids**:
- Network solids, also known as covalent network solids, are materials where atoms are bonded by covalent bonds in a continuous network. This means that the entire solid can be considered as a single giant molecule.

2. **Analyzing Each Option**:
- **SO2 (Sulfur Dioxide)**:
- SO2 consists of individual molecules held together by weaker intermolecular forces (like van der Waals forces). Therefore, it is not a network solid.

- **I2 (Iodine)**:
- I2 is a diatomic molecule, consisting of individual I2 molecules. It does not form a continuous network of covalent bonds, so it is also not a network solid.

- **Diamond**:
- Diamond is a form of carbon where each carbon atom is covalently bonded to four other carbon atoms in a three-dimensional tetrahedral structure. This creates a continuous network of covalent bonds throughout the entire solid, making diamond a network solid.

- **H2O (Water)**:
- Water is composed of individual H2O molecules that are held together by hydrogen bonds. It does not form a continuous network of covalent bonds, so it is not a network solid.

3. **Conclusion**:
- Based on the analysis, the only option that qualifies as a network solid is **diamond**.

### Final Answer:
The correct answer is **diamond**.
