Metals as Conductors Flashcards

All 4 cards in this deck

Why are metals good conductors of electricity?

The delocalised electrons carry electrical charge through the metal.

Why are metals good conductors of thermal energy?

Thermal energy is transferred by the delocalised electrons.

True or false? Metals conduct electricity because their ions are free to move.

False. It is the delocalised electrons that move and carry the charge; the metal ions stay in place.

True or false? A substance with a high melting point that conducts electricity as both a solid and a liquid is likely to be a metal.

True. Metals have delocalised electrons that carry charge in the solid and liquid state.
