Metals as Conductors | AQA GCSE Combined Science: Trilogy …

How do metals conduct electricity? Metals consist of giant structures. Within the metal lattice, the atoms lose their outer electrons and become positively charged metal ions. The outer electrons no longer belong to any specific metal atom and are said to be delocalised. Metals can conduct electricity because the delocalised electrons are able to move through the …
