Fluorine is a stronger oxidizing agent than chlorine because despite having a lower electron affinity, its smaller size and higher electronegativity allow it to attract electrons more strongly, making it more reactive. This stronger ability to attract electrons results in a higher tendency for fluorine to gain electrons and undergo reduction reactions, which characterizes it as a stronger oxidizing agent compared to chlorine.
Generally electron affinity goes up as you go from left to right across the periodic table, and decreases as you go down a column. However, fluorine is an exception -- and the element with the highest electron affinity is chlorine.(Note that the most electronegative element is fluorine however; 'electronegativity' is not exactly the same as 'electron affinity'.)Electronegativity is the ability of an atom in a molecule to draw bonding electrons to itselfElectron affinity is a measure of the energy change when an electron is added to a neutral atom to form a negative ion.The reason that the electron affinity is not as high as might otherwise be predicted for fluorine, is that it is an extremely small atom, and so it's electron density is very high. Adding an additional electron is therefore not quite as favorable as for an element like chlorine where the electron density is slightly lower (due to electron-electron repulsion between the added electron and the other electrons in the electron cloud).
Fluorine is more oxidizing than chlorine because it is smaller in size with higher electronegativity, which enables it to attract electrons more strongly. This makes it more effective at gaining electrons to achieve a stable electron configuration, leading to stronger oxidizing properties compared to chlorine.
chlorine has the highest electron affinity
Chlorine has a negative second electron affinity because it releases energy when gaining an additional electron. This makes it less likely to accept a second electron compared to its first electron affinity, which is positive.
Chlorine (Cl) has the most negative electron affinity among these elements. It has a higher tendency to gain an electron to form a chloride ion compared to aluminum (Al), silicon (Si), and sulfur (S).
Electronegativity is the measure of pull one atom has on another. Electron affinity is the amount of energy that is released when a neutral atom gains an electron.

Electronegativity is the measure of pull one atom has on another. Electron affinity is the amount of energy that is released when a neutral atom gains an electron.
Electron affinity is related to the formation of anions; electronegativity is related to the formation of cations.

Fluorine has the highest electron affinity because it has a small atomic size and high effective nuclear charge, which results in a strong attraction between the nucleus and incoming electrons. This strong attraction allows fluorine to readily accept an additional electron and achieve a stable electron configuration.
Chlorine (Cl) has the most negative electron affinity among these elements. It has a higher tendency to gain an electron to form a chloride ion compared to aluminum (Al), silicon (Si), and sulfur (S).
Electronegativity is the measure of pull one atom has on another. Electron affinity is the amount of energy that is released when a neutral atom gains an electron.
Fluorine has higher electron affinity than any other element.
Chlorine has a high electron affinity due to its tendency to gain an electron to achieve a stable electron configuration. It also has a relatively low ionization energy, meaning it takes less energy to remove an electron from a chlorine atom compared to other elements.
