It becomes a negative ion.
When a chlorine atom gains an electron in to its outer most energy shell ( reduction) it becomes the chloride anion. Cl(g) + e^- = Cl^-(g)
A sodium atom has one valance electron which it donates to a chlorine atom which has seven valance electrons; as a result of this electron exchange, both the sodium and the chlorine will then have complete outer electron shells, and they also will both become electrically charged ions which will attract each other.

It would gain or share an electron - in order to complete the outer shell.
A sodium atom has one valance electron which it donates to a chlorine atom which has seven valance electrons; as a result of this electron exchange, both the sodium and the chlorine will then have complete outer electron shells, and they also will both become electrically charged ions which will attract each other.
None - the electron goes from sodium TO the chlorine.
