Atoms in a metal are arranged in a lattice formation. Metallic bonding is the electrostatic attraction between positive metal ions and delocalised electrons. A series of free IGCSE Chemistry Activities and Experiments (Cambridge IGCSE Chemistry). Maths. No free electrons exist in this structure, so it it contributes to the “sea of delocalised electrons”, thereby being able to conduct heat and electricity well.​ This is why graphite is often used for electrodes in electrolysis.
