Question

Why is diamond a bad conductor of electricity?

Answer 1

Diamond:

• Diamond is a carbon allotrope.
• Diamond has a three-dimensional network of regular tetrahedrons in which each carbon atom is attached to the other four carbon atoms through strong covalent bonds.
• Structure of diamond:

Diamond is a bad conductor of electricity:

• 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.
