Which type of solids are good conductor of electricity and are in malleable in nature?

Options

A. lonic solids
B. Metallic solids
C. Molecular solids
D. Amorphous solids

Explanation

To answer the question "Which type of solids are good conductors of electricity and are malleable in nature?", we can follow these steps:

### Step 1: Identify the Properties
The question specifies two properties:
1. Good conductor of electricity
2. Malleable in nature

### Step 2: Understand the Types of Solids
There are different types of solids, including:
- Metals
- Ionic solids
- Molecular solids
- Amorphous solids

### Step 3: Analyze Each Type of Solid
1. **Metals**:
- Metals are known to be good conductors of electricity due to the presence of free electrons that can move easily through the metal lattice.
- Metals are also malleable, meaning they can be hammered or pressed into thin sheets without breaking.

2. **Ionic Solids**:
- Ionic solids, such as sodium chloride (NaCl), do not conduct electricity in solid form. They can conduct electricity when melted or dissolved in water, but they are not malleable; they tend to break when force is applied.

3. **Molecular Solids**:
- Molecular solids, like ice, do not conduct electricity and are not malleable. They tend to break rather than deform under pressure.

4. **Amorphous Solids**:
- Amorphous solids, such as glass, are insulators and are also not malleable.

### Step 4: Conclusion
Based on the analysis, the type of solids that are good conductors of electricity and are malleable in nature is **metallic solids**. Examples of metallic solids include silver (Ag), gold (Au), copper (Cu), and aluminum (Al).

### Final Answer
**Metallic solids are good conductors of electricity and are malleable in nature.**
