Why Electron affinity of Fluorine is less than Chlorine?
I want to know why the electron affinity of Fluorine is less than Chlorine?
The electron affinity of an atom refers to the amount of energy released when an electron is added to a neutral atom in the gaseous state to form a negative ion. In the case of Fluorine and Chlorine, the electron affinity of Fluorine is less than Chlorine because the atomic radius of Fluorine is smaller than that of Chlorine. Consequently, it is more difficult to add an electron to Fluorine as compared to Chlorine, which has a larger atomic radius.
