me·tal·lic bond

(mə-tăl′ĭk) The chemical bonding that holds the atoms of a metal together. This bond is formed from the attraction between mobile electrons and fixed, positively charged metallic atoms.

Metallic Bond

 

a type of bond between atoms in crystalline materials that are metallic in nature (metals and intermetallic compounds). The metallic bond results from a high concentration of quasi-free electrons in the materials (conduction electrons). The negatively charged electron gas “bonds” the positive ions to one another.

metallic bond

[mə′tal·ik ′bänd] (physical chemistry) The type of chemical bond that is present in all metals, and may be thought of as resulting from a sea of valence electrons which are free to move throughout the metal lattice.
