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.
