The correct Answer is:
To determine the characteristics generally shown by metals from the given list, we will analyze each characteristic one by one.
### Step-by-Step Solution:
1. **Identify Good Conductors**:
- Metals are known for being good conductors of electricity and heat. This is because they have free electrons that can move easily.
- **Conclusion**: Metals exhibit this characteristic.
2. **Examine Transparency**:
- Metals are typically not transparent. Instead, they are opaque, meaning they do not allow light to pass through.
- **Conclusion**: Metals do not exhibit transparency.
3. **Assess Lustrous Property**:
- Metals have a shiny appearance, which is referred to as being lustrous. This property allows them to reflect light effectively.
- **Conclusion**: Metals exhibit this characteristic.
4. **Consider Solid State**:
- Most metals are solid at room temperature (with the exception of mercury). They maintain a definite shape and volume.
- **Conclusion**: Metals exhibit this characteristic.
5. **Check Opaqueness**:
- As mentioned earlier, metals are opaque, meaning they do not allow light to pass through them.
- **Conclusion**: Metals exhibit this characteristic.
6. **Look at Insulators**:
- Metals are not insulators; instead, they are conductors. Insulators are materials that do not conduct electricity.
- **Conclusion**: Metals do not exhibit this characteristic.
### Summary of Characteristics:
From the analysis, the characteristics that metals generally show are:
- Good conductors (i)
- Lustrous (iii)
- Solid (iv)
- Opaque (v)
### Final Answer:
The characteristics generally shown by metals are:
- Good conductors (i)
- Lustrous (iii)
- Solid (iv)
- Opaque (v)
To determine the characteristics generally shown by metals from the given list, we will analyze each characteristic one by one.
### Step-by-Step Solution:
1. **Identify Good Conductors**:
- Metals are known for being good conductors of electricity and heat. This is because they have free electrons that can move easily.
- **Conclusion**: Metals exhibit this characteristic.
