Metallic bonds can conduct electricity. It depends on what type of metal you use because everything has a different chemical make up and different bond. Metallic bonds make it easy for some metals to be ductile meaning that they can be stretched into thin wires and they can also be malleable which means they can be pound into thin sheets. Also certain atoms will react with water to make rust.
