Question

Which of the following is true for a metallic solid?

• A. They are malleable and ductile.
• B. They possess lusture
• C. The do not conduct electricity in solid state, but conduct electricity in molten state.
• D. Both (a) and (b)

Answer 1

The correct option is D Both (a) and (b)

Characteristics of metallic solids:

1. Have a wide range of ​melting points.
2. They posses lusture, and coloured in certain cases
3. Show high thermal and ​electrical conductivity.
4. Show high thermal and ​electrical conductivity​ ,due to the presence of free and mobile electrons​.
5. They conduct electricity in solid as well as in molten state​
