To determine the characteristics generally shown by metals from the provided list, we can analyze each characteristic one by one:
1. **Good Conductors**: Metals are known for being good conductors of electricity and heat. This is one of the primary characteristics of metals. Therefore, this characteristic applies to metals.
2. **Transparent**: Metals are typically not transparent. In fact, they are usually opaque, meaning they do not allow light to pass through. Therefore, this characteristic does not apply to metals.
3. **Lustrous**: Metals have a shiny appearance, which is referred to as being lustrous. This characteristic applies to metals, as they reflect light well.
4. **Solid**: Most metals are solid at room temperature (with the exception of mercury). Thus, this characteristic applies to metals.
5. **Opaque**: As mentioned earlier, metals are opaque and do not allow light to pass through. This characteristic applies to metals.
6. **Insulators**: Metals are not insulators; they are conductors. Insulators do not conduct electricity well, which is the opposite of what metals do. Therefore, this characteristic does not apply to metals.
Now, summarizing the applicable characteristics for metals:
- Good Conductors (i)
- Lustrous (iii)
- Solid (iv)
- Opaque (v)
Thus, the characteristics generally shown by metals are **Good Conductors, Lustrous, Solid, and Opaque**.
### Final Answer:
The characteristics generally shown by metals are (i) Good conductors, (iii) Lustrous, (iv) Solid, and (v) Opaque.
