Metallic Bonding Metallic Bonding Why do metals conduct electricity? Metals conduct electricity. The delocalised electrons are free to move throughout the structure in 3-dimensions. They can cross grain boundaries. Even though the pattern may be disrupted at the boundary‚ as long as atoms are touching each other‚ the metallic bond is still present. Liquid metals also conduct electricity‚ showing that although the metal atoms may be free to move‚ the delocalisation remains in force until the
