In terms of Electrostatic Forces, Suggest why the ‘Electron Affinity’ of Fluorine has a Negative value.

Electron affinity is the energy released when 1 mole of gaseous atoms each acquire an electron to form 1 mole of gaseous 1- ions. Fluorine has a negative value as energy is released when the electron is gained. This is because there is an attraction between the protons in the nucleus and the added electrons.
