Conducting Electricity in Giant Ionic Structures
Giant ionic structures can conduct electricity when they are in solution or when they are molten. Giant ionic structures CANNOT conduct electricity when they are solid.

Giant ionic structures
- One way substances can conduct electricity is using delocalised electrons to carry a charge.
- Giant ionic structures do NOT have any delocalised electrons.
Solid giant ionic structures
- Ions are fixed in position in solid giant ionic structures.
- This means ions are unable to move current across the structure.
- The ions can't carry a charge which means solid giant ionic structures can't conduct electricity.
Molten giant ionic structures
- Ions are able to move in molten giant ionic structures.
- This means ions are able to carry a charge across the structure.
- The ions can carry a charge which means molten giant ionic structures can conduct electricity.
Giant ionic structures in solution
- Ions are able to move when giant ionic structures are in solution.
- This means ions are able to carry a charge across the solution.
- The ions can carry a charge which means giant ionic structures can conduct electricity in solution.
