Im gping to help you like this: In ZnF2 , you have a lattice of Zn2+ ions and F− ions. So you can re-write your equation as: Zn→Zn2++2e− F2+2e−→2F− 
I think with this you may know how to proceed. May this help you a lot

Answer : [tex]F_2[/tex] reactant is reduced and [tex]Zn[/tex] reactant is oxidized.

Explanation :

Redox reaction : It is a type of reaction in which an oxidation and reduction reaction takes palace simultaneously.

Oxidation : The loss of electrons or increase in the oxidation number is an oxidation.

Reduction : The gain of electrons or decrease in the oxidation number is a reduction.

The given balanced redox reaction is,

[tex]F_2+Zn\rightarrow ZnF_2[/tex]

The oxidation number of [tex]F_2[/tex] = 0

The oxidation number of [tex]Zn[/tex] = 0

The oxidation number of Zn in [tex]ZnF_2[/tex]

x + 2(-1) = 0

x = +2

The oxidation number of [tex]F_2[/tex] in [tex]ZnF_2[/tex] = -1

That means [tex]F_2[/tex] is reduced due to decrease in the oxidation number from 0 to (-1) and 'Zn' is oxidized  due to increase in the oxidation number from 0 to (+2).

Therefore, [tex]F_2[/tex] reactant is reduced and [tex]Zn[/tex] reactant is oxidized.
