WebMetals contain free moving delocalized electrons. When electric voltage is applied, an electric field within the metal triggers the movement of the electrons, making them shift from one end to another end of the conductor. Electrons will move toward the positive side. Metal is a good conduction of heat. WebMay 20, 2024 · As a result, metals are good conductors of electricity. As seen in the table above, the melting points of metallic crystals span a wide range. Figure 12.7.2: Metallic crystal lattice with free electrons able to move among positive metal atoms.
