Choose the incorrect information about metals:

Options

A. metals are lustrous
B. metals are brittle
C. metals are sonorous
D. metals are ductile

Explanation

To determine the incorrect information about metals from the given options, we can analyze each statement one by one. Here’s a step-by-step solution:

### Step 1: Understand the Properties of Metals
- Metals are known for certain properties. We need to evaluate each property mentioned in the options to identify which one is incorrect.

### Step 2: Evaluate Each Statement
1. **Metals are lustrous**:
- This statement is true. Metals have a shiny appearance due to their ability to reflect light.

2. **Metals are sonorous**:
- This statement is also true. Metals produce sound when struck, which is referred to as being sonorous.

3. **Metals are ductile**:
- This statement is true as well. Ductility is the property of metals that allows them to be drawn into wires.

4. **Metals are brittle**:
- This statement is incorrect. Metals are generally not brittle; they are malleable and ductile, meaning they can be shaped and stretched without breaking. Brittle materials, like glass or ceramics, break easily when force is applied.

### Step 3: Identify the Incorrect Information
- The incorrect statement among the options provided is that "Metals are brittle." This is not true, as metals are known for their ductility and malleability.

### Conclusion
- The incorrect information about metals is that they are brittle.
