What bond is formed by a sea of delocalized electrons?

Explanation:
A sea of delocalized electrons corresponds to metallic bonding. In a metal, the valence electrons are not tied to any one atom; they move freely around a lattice of positively charged metal ions. This shared electron cloud holds the ions together through electrostatic attraction between the moving electrons and the fixed ions. The result is a cohesive, conductive structure that explains why metals conduct electricity and are malleable and ductile, since layers can slide without breaking the overall bond. This differs from ionic bonding, which relies on transfer of electrons to form fixed ions that attract, covalent bonding, which involves localized electron pairs shared between specific atoms, and hydrogen bonding, which are weaker intermolecular attractions.
