Short explanation

Electrical conductivity in metals is explained by the presence of delocalised electrons. In metallic bonding, positive metal ions are surrounded by a sea of these delocalised electrons, which are free to move throughout the structure. This mobility allows metals to conduct electricity effectively, as the delocalised electrons can carry an electric charge when a potential difference is applied. Therefore, the ability of metals to conduct electricity is directly linked to their metallic bonding and the presence of these mobile charged particles.

Misunderstanding Conductivity: Remember that electrical conductivity in metals is due to the movement of delocalised electrons. The formula for conductivity can be understood as the ability of these electrons to move freely through the metallic lattice, allowing electric current to pass. Therefore, focus on how the structure of metals allows these electrons to move, leading to high conductivity.
