In metallic bonding, move freely between neighboring atoms. metals are ductile because the forces that hold their atoms together are .

Answer;

Metallic bond

Explanation;Metallic bonds are forces of attraction that hold metal atoms together. These bonds result from the attraction between negatively charged electrons and positively charged nucleus of metal atoms.Metallic bond is the force that binds metals together. Metals are malleable and ductile because when a force causes metal ions to move past each other, layers of ions are still held together by delocalized electrons between them.
