Explanation: Due to their bonding, metallic solids have delocalised electrons. These free electrons can move around, therefore can conduct electricity.

Do metals or nonmetals conduct electricity in solid state?

2 Answers. NO, they cannot conduct electricity. Because they have no Free mobile electron. We all know that in solid electrons are carrier of electricity while ions are carrier in liquids.

Why do metals not conduct electricity in solid state?

because, in solid state, the ions are held together in fixed positions by strong electrostatic forces and cannot move freely.
