Short explanation

Explain that outer-shell electrons in metals are delocalised. This objective belongs to Metallic bonding within Chemical bonds, ionic, covalent and metallic for AQA GCSE Chemistry 8462. A strong answer should use delocalised accurately, explain the chemistry behind the statement, and connect the idea back to the exact command in the objective. When revising, separate this point from neighbouring Chemistry ideas by naming the relevant particle, substance, process, calculation, observation, or structure before giving the final conclusion.
