Question

ccc structure and function when copper wires are made, a copper rod is pulled into a narrower wire. explain how metallic bonding allows this to happen.

Explanation:

Metallic bonding involves a sea of delocalized electrons surrounding metal cations. When a copper rod is pulled into a wire, the cations can slide past each other while still being held together by the electron - sea. The electrons are mobile and can adjust to the new shape, allowing the metal to be ductile.

Answer:

In metallic bonding of copper, there is a sea of delocalized electrons surrounding copper cations. When pulled into a wire, the cations can slide relative to each other while the delocalized electrons maintain the bonding, enabling the copper to be drawn into a narrower wire due to its ductility provided by the metallic bonding structure.
