A sample of pure metallic copper is examined at the particulate level.
Copper atoms each contribute one valence electron that is not associated with any specific nucleus.
(a) Define the term "sea of delocalized electrons" as it applies to metallic solids.
(b) State two structural features that distinguish a metallic solid from an ionic solid of similar lattice geometry.
(c) Identify the mobile charge carriers that allow a solid piece of copper to conduct an electric current.
