Diamond is a bad conductor because of ?
Correct answer: B. No free electron
- A. High density
- B. No free electron
- C. Tight structure
- D. Transparent to light
Explanation
Since each carbon atom is attached to the other four carbon atoms through strong covalent bonds. Hence, no free electrons are present in the diamond crystal. Due to the absence of free electrons, diamond is a poor electrical conductor.

About Crystalline Solids
Crystalline solids contain particles arranged in a regular repeating lattice described by a unit cell. Their study includes coordination number, packing efficiency, density, anisotropy, cleavage, polymorphism and common crystal systems, along with ionic, molecular, covalent network and metallic crystals. Crystalline order differs from the random arrangement of amorphous solids.
