Answer 1

Answer:

Sodium is a metal, which means it has lattice structure in its solid state. Its molecules are held together strongly in this form. However, when it is melted, heat energy is provided to the molecules to break apart against the attractive forces due to other molecules. Thus, the ions now become free to move, and carry charges, so they conduct electricity. In aqueous solution, the ions are again free to move, as water overcomes the force of attraction between the molecules, and hence the ions conduct electricity.

Answer 2

Answer:

When NaCl is in its Solid State it does not have any Free electrons. Conduction of electricity is due to presence of free electrons. But when the compound comes to its Molten State, then due to high energy it loses some electrons due to which it becomes capable of conducting ELECTRICITY.
