Explain this

In solid NaCl there are no delocalized electrons which are free to move within the crystal lattice to conduct electricity, nor can the slightly charged atoms move. When NaCl solid dissolves in water the chemical bonds are broken and the electrons involved n bonding move to the more electronegative chlorine atoms, forming chloride ions, Cl-. In solution, these charged ions, Na+ and Cl-, are free to move about and in so doing conducting electricity.when a voltage is applied.
