Why chlorine has highest electron affinity than fluorine?

Chlorine has the highest electron affinity because the electron affinity of fluorine is little less . The EA of fluorine is less due to its compact size as a result of which incoming electrons face repulsion . … Chlorine has more size than fluorine because it has an additional/extra number of shell than fluorine .

Which has highest electron affinity of CL?

Therefore, chlorine has a higher electron affinity than fluorine, and this orbital structure causes it to have the highest electron affinity of all of the elements.

What causes higher electron affinity?

Electron affinity increases upward for the groups and from left to right across periods of a periodic table because the electrons added to energy levels become closer to the nucleus, thus a stronger attraction between the nucleus and its electrons.

Which electron has the highest electron affinity?

Fluorine
Fluorine has highest electron affinity in the periodic table.
