Question #37a44

Answer 1

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.
