Sodium chloride and sodium metal can both conduct electricity under differing conditions. Give the conditions required for each to conduct electricity and explain how each conducts electricity.
Sodium chloride will conduct electricity only when it is in a liquid state or in solution, this is because the ions are free to move in this state, allowing them to carry charge and conduct electricity. Sodium metal will conduct electricity in both a solid and liquid state, due to 'a sea' of delocalised electrons which can move and are able to carry charge.
