While it's true that when a crystal of the ionic substance sodium chloride is dissolved in water the sodium and chloride ions separate from one another, they do not separate to form lumps of sodium metal or to form chlorine gas.
Rather, they remain as single
Ions of a substance do not have the same properties as larger quantities of the substance, which are differently bonded together.
This is an interesting discussion, since solid sodium chloride contains ionic bonds, solid sodium metal contains and chlorine gas contains covalent bonds.
