So let me know if I'm thinking about this the wrong way. From my understanding "electron affinity" is the amount of energy released when an atom gains an electron.

So does that mean that if i add 1 electron to one florine atom that 328 kj/mol of energy will be released when it receives the electron?

I don't know if that's the correct value, but the atom must be in the excited state (missing an electron) to have that energy released when it recaptures an electron.
And that energy is for a mole of fluorine atoms, not one atom.

Neutral atoms do not have much of a tendency to "capture" additional electrons. I'm not sure I understand the conditions of this particular Gedankenexperiment.
