Question

For each ionic compound below determine the formula and the cation anion ( metal:nonmetal) ratio.Ionic compound 1.

Answer 1

The first shown ionic compound has only two elements, Li and F.

On a periodica table, we can see that Li is on the first group, so it is the metal one.

F is on the 17th group, so it is the nonmetal.

We have only one of each of them, so the formula will only have one of each.

The formula is:

`LiF`

And we have 1 of each, so their ratio is 1:1.
