Dissociation Question

I was doing a problem where MgF2 dissociated to Mg and 2F. Since F is a super 7, why did it dissociate to 2F instead of F2? Is there a general rule to know what form the super 7 elements will dissociate in?

PS This was a Ksp question and as such, the coefficient matters because if it's 2F I would need to raise [F] to the power of 2 while if it was F2 I wouldn't need to raise it to any power.
