A solid is a good conductor of electricity. It is alos malleable and ductile. Predict its nature.

Answer

To determine the nature of the solid described in the question, we can analyze the properties mentioned: good electrical conductivity, malleability, and ductility. Here’s a step-by-step solution:

### Step 1: Identify the Properties
The solid is described as:
- A good conductor of electricity
- Malleable
- Ductile

### Step 2: Relate Properties to Types of Solids
- **Good Conductors of Electricity**: Typically, metals are known for their ability to conduct electricity due to the presence of free-moving electrons.
- **Malleability**: This property allows a material to be hammered or pressed into shape without breaking. Metals are generally malleable.
- **Ductility**: This refers to the ability of a material to be stretched into a wire. Metals are also ductile.

### Step 3: Conclude the Nature of the Solid
Given that the solid is a good conductor of electricity, malleable, and ductile, it can be concluded that the solid is a **metal**. Metals have a structure characterized by a lattice of positive ions surrounded by a "sea of electrons," which allows them to exhibit these properties.

### Final Answer
The nature of the solid is that it is a **metal**.
