Answer:

See below

Explanation:

I think the idea here may be to realize that since #NaCl# or sodium chloride is an ionic compound, the formula given is not the molecular formula, but instead is the formula unit .

The formula unit is the simplest repeating unit within the crystal lattice of the ionic compound.

You could realize that #Na^+# has one valence electron and that #Cl^-# has eight valence electron and draw a lewis dot structure:

#Na-Cl#

realizing that the bond formed between them is ionic, and that the electron will be much closer to the species #Cl#.

In fact, because of this, the species #NaCl# readily dissolves in water, since the ion

#Na^+# are attracted to #delta^-#
and
#Cl^-# are attracted to #delta^+#

about the water molecule.
