STEP-BY-STEP EXPLANATION:
Generally, metals are ductile because of metallic bonds which are found mainly in metal.
In a metallic bond, valence electrons are delocalized and shared between many atoms.
Copper is a metal and it has the properties of a metal.
Copper is ductile because it contains a metallic bond which is the metallic structure
The metallic structure shows how the atoms of copper are being arranged. How closely packed the atoms are and the bond that exists between the atoms. The atoms are in crystal
