Which one has greater electronic affinity and why? cl or f

1.	Which one has greater electronic affinity and why? cl or f
Answer» ANSWER: Chlorine Explanation: Fluorine, which is higher up the group then chlorine, has a lower ELECTRON affinity. This is because the electrons in the outermost shell of a fluorine atom are closer TOGETHER. ... Energy is REQUIRED to keep the GAINED electron in the shell, causing fluorine to have a smaller electron affinity than chlorine.
