Nettet7. apr. 2024 · The primary difference between electronegativity and electron affinity lies in the fact that electronegativity is the property related to the ability of an electron to attract towards an atom. On the other hand, electron affinity is related to the release of energy whenever an electron tends to get added to an atom. Nettet15. sep. 2024 · Which has higher electron affinity fluorine or neon? In the modern periodic table, electron affinity increases on moving left to right in a period while it decreases on moving down the group. Thus, noble gases have the least electron affinity in a period. Hence, we can conclude that in a period, fluorine (halogen) has higher …
