Question

What is the chemical formula of ionic compound for NaF?

Answer 1

Sodium flouride

Explanation:

Since `Na` is a metal and `F` is a nonmetal, these two can combine together to form an ionic bond.

We know that `Na` tends to have an oxidation state of `+1`, so it becomes `Na^+`.

Fluorine always has an oxidation state of `-1`, so its ion is `F^-`.

Combining together

`Na^+F^-`

we get

`NaF`

To name an ionic compound, the cation (positive ion) is named first, and the anion (negative ion) is named last with a suffix of "-ide".

So, the compound's name will be sodium fluoride.
