The Properties of Metals
Chemistry: Cambridge International GCSE Supplement, topic 2.7.2
Metals as Conductors
Metals conduct heat and electricity well. This is because of the delocalised electrons that are around the layers of positive ions.

Electrical conductors
- Metals are good conductors of electricity because their delocalised electrons can carry a charge through the structure.
- The electrons move from the negative terminal to the positive terminal.
Heat conductors
- The same delocalised electrons can also carry heat energy through the structure.
