EXPLAIN the following trend and anomalies observed on the electron affinities of elements in the halogen family in the periodic table. Electron affinity generally decreases from top to bottom down a group, but it increases slightly from fluorine (-328 kJ) to chlorine (-349 kJ). Why does fluorine has lower electron affinity than chlorine?
