Sodium fluoride would be NaF, calcium fluoride would be #CaF_2#.

Sodium has an oxidation number of #Na^+# and fluorine is #F^-# for a neutral compound of NaF.

Calcium has an oxidation number of 2+ while fluorine has an oxidation of 1-, so two atoms of fluorine are needed to neutralize the 2+ charge on calcium.

In terms of bond, they would both be ionic compounds, so they do not differ in that regard.
