Question

Is `NaF` neutral?

Answer 1

Yes.

Explanation:

It is neutral because the `Na`and `F` atoms are transferring their valence electrons in order to become stable. This results in an overall stable atom. If we were to identify the individual charges of said atoms, `Na` would have a positive charge, and `F` a negative charge - both of 1.

Answer 2

`"Absolutely!"`

Explanation:

Sodium fluoride is conceived to be composed of equal numbers of `Na^+` and `F^-` ions that are electrostatically bonded together in an extended, non-molecular array. And therefore sodium fluoride is neutral.

See here.

Aqueous solution of sodium fluoride are slightly basic given the basicity of the fluoride ion:

`F^(-) + H_2O(aq) rightleftharpoons HF(aq) + HO^-`
