Question

Which element forms an ionic bond with flurorine?

Answer 1

Well, most metals do....

Explanation:

Fluorine is the most oxidizing element on the Periodic Table.

`1/2F_2+e^(-) rarrF^(-)` `;E^@=2.87*V`

And certainly the alkali metals and alkaline earths form ionic fluorides....i.e. `M^(+)F^(-)` or `M^(2+)F_2^(-)`.

Most fluoride salts give solutions that are slightly basic. Why should this be so?
