Electron affinity is the ability of an atom to pull electrons toward itself. Fluorine and the rest of the elements in the group have a high electron affinity, meaning that they have a strong tendency to pull electrons toward themselves because they are only one electron away from filling up their octet. On the other hand, elements like lithium and the rest of its group don't have a tendency to pull electrons in because it would be easier to have an octet by removing their valence electrons.

electron affinity increases from left to right and increases from bottom to top, thereby making fluorine the most electron affinitive. (if that's a word)

Electron Affinity is the energy associated with the addition of an electon to a gaseous atom. It increases from left to right (period) and decreases from the top to the bottom (group)
