Incorrectly matched characteristic is:

Options

A. `S_(8)`: Covalent lattice
B. `P_(4)`: Tetrahedron
C. `S_(4)^(2-):`Zig-Zig
D. `SiO_(2)`: Covalent lattice

Explanation

To solve the question regarding the incorrectly matched characteristic, we will analyze each option provided in the question step by step.

### Step 1: Analyze S8
- **Characteristic**: S8 covalent lattice
- **Analysis**: The S8 molecule has a crown ring structure, where each sulfur atom forms two bonds. The structure is not a covalent lattice; instead, it is held together by weak Van der Waals forces between the bulky S8 molecules. Therefore, this characteristic is incorrectly matched.

### Step 2: Analyze P4
- **Characteristic**: P4 tetrahedron
- **Analysis**: The P4 molecule (white phosphorus) has a tetrahedral structure. Each phosphorus atom in P4 is bonded to three other phosphorus atoms, forming a tetrahedral shape. This characteristic is correctly matched.

### Step 3: Analyze S4 2-
- **Characteristic**: S4 2- zigzag
- **Analysis**: The S4 2- ion has a zigzag structure. Each sulfur atom can form two bonds, and the arrangement results in a zigzag pattern. This characteristic is correctly matched.

### Step 4: Analyze SiO2
- **Characteristic**: SiO2 covalent lattice
- **Analysis**: In SiO2, each silicon atom is covalently bonded to four oxygen atoms, forming a three-dimensional network structure. This characteristic is correctly matched as a covalent lattice.

### Conclusion
Based on the analysis:
- The incorrectly matched characteristic is **S8 covalent lattice**.

### Final Answer
The incorrect characteristic is: **S8 covalent lattice**.
