SUMMARY
Chlorine exhibits a higher electron affinity than fluorine due to its larger atomic radius, which allows for a more favorable interaction with incoming electrons. Fluorine, despite being the most electronegative element, has a smaller atomic radius that creates electron-electron repulsion in its crowded electron cloud, making it less effective at attracting additional electrons. This phenomenon highlights the importance of atomic structure in determining chemical properties.
