The simplest model of metallic bonding is the "sea of electrons" model, which imagines that the atoms sit in a sea of valence electrons that are delocalized (spread out) over all the atoms.

This structure facilitates efficient electrical and thermal conductivity, imparts luster through light interaction, and allows metals to be ductile and malleable, enabling shaping without breaking, in contrast to brittle ionic compounds. Overall, these properties are closely tied to the nature of metallic bonds.
