`[SiO_(4)]^(4-)` has tetrahedral structure, the silicate formed by using the three oxygen has

Options

A. sheet silicate
B. double-chain silicate
C. chain silicates
D. three-dimensional silicates

Explanation

To solve the question regarding the silicate formed by using three oxygen atoms from the tetrahedral structure of `[SiO_(4)]^(4-)`, we will analyze the types of silicates and determine which one shares three oxygen atoms.

### Step-by-Step Solution:

1. **Understanding the Tetrahedral Structure**:
- The silicate ion `[SiO_(4)]^(4-)` has a tetrahedral geometry, meaning that the silicon atom is at the center and the four oxygen atoms are positioned at the corners of a tetrahedron.

2. **Identifying Silicate Types**:
- Silicates can be categorized into different types based on how the tetrahedra share oxygen atoms. The main types are:
- **Nesosilicates** (isolated tetrahedra)
- **Sorosilicates** (double tetrahedra)
- **Cyclic silicates** (ring structures)
- **Chain silicates** (single and double chains)
- **Sheet silicates** (two-dimensional sheets)
- **Framework silicates** (three-dimensional structures)

3. **Analyzing the Options**:
- We need to find a silicate that shares three oxygen atoms.
- **Chain Silicates**: In chain silicates, two oxygen atoms are shared between tetrahedra.
- **Double Chain Silicates**: In double chain silicates, some tetrahedra share two oxygen atoms while others share three; hence, this does not fit our requirement.
- **Sheet Silicates**: In sheet silicates, three oxygen atoms are shared among the tetrahedra, leaving one oxygen atom unshared. This fits our requirement perfectly.
- **Three-Dimensional Silicates**: In three-dimensional silicates, all four oxygen atoms are shared, which does not meet our criteria.

4. **Conclusion**:
- The correct answer is that the silicate formed by using three oxygen atoms is a **sheet silicate**. This is the type of silicate where three oxygen atoms are shared among adjacent tetrahedra.

### Final Answer:
The silicate formed by using three oxygen atoms from `[SiO_(4)]^(4-)` is a **sheet silicate**.
