In the mark scheme it mentions 'delocalised electrons from the outer shell' 'free to move' and 'energy transferred through the structure'. Online it mentions sodium conducting when it's in a molten state'. Help!

Electrical conductivity: The electrons are free to move over the whole structure (delocalised) and so can move towards a positive potential and away from a negative potential.
