WebbThe structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties. WebbMetallic bonds are formed when the charge is spread over a larger distance as compared to the size of single atoms in solids. Mostly, in the periodic table, left elements form metallic bonds, for example, zinc and copper. Because metals are solid, their atoms are tightly packed in a regular arrangement.
