The reaction is
2NaCl + CaF2 --> 2NaF + CaCl2
and the enthalpies of formation (kJ/Mol) of the solids at STP are
2NaCl = (-411)*2
CaF2 = -1220
Total = -2042
2NaF = (-469)*2
CaCl2 = -796
Total = -1734
The calculations show that the reactants are more stable than the products by some 307kJ/mol, so that the reaction would not proceed. (For more advanced readers, the value for the Gibbs free energy of formation will not be very much different from this, as the entropy terms will be relatively small in comparison with the enthalpy terms.) A major factor in this is the relatively high lattice enthalpy of CaF2.

What is the chemical formula for calcium and fluorine?
Fluorine, the element has a symbol/"formula" F. As a charged ion it has a -1 charge = F- Otherwise, fluorine is a diatomic molecule= F2 Calcium is also an element with symbol/"formula" Ca. As an ion it has a +2 charge, so it can be written as Ca2+.
