Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Among the given options, Diamond is a bad conductor of electricity.
Additional Context:
- Diamond is an allotrope of carbon with a tetrahedral structure that doesn't allow free electrons.
- Good conductors in the list:
- Gold: Excellent conductor (used in high-end electronics)
- Silver: Best metallic conductor (highest electrical conductivity)
- Graphite: Conducts electricity due to delocalized electrons in its layered structure
- Key difference:
- Diamond is an electrical insulator but excellent thermal conductor
- Graphite conducts electricity despite being a non-metal
Correct Answer: (1) Diamond.
