Which element has higher electron affinity?
Verified Answer
Which element has higher electron affinity?
As fluorine sits atop chlorine in the periodic table, most people expect it to have the highest electron affinity, but this is not the case. Fluorine is a small atom with a small amount of space available in its 2p orbital. Because of this, any new electron trying to attach to fluorine experiences lower electron affinity from the electrons already living in the element's 2p orbital. Since chlorine's outermost orbital is a 3p orbital, there is more space, and the electrons in this orbital are inclined to share this space with an extra electron. 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.

Which element has higher electron affinity?
Chlorine has more electron affinity(E.A) than fluorine becoz due to its small size there is more electron cloud and repulsion occurs btw electron due to this reason Cl has more E.A than F and while we move from top to bottom along the group E.A increases
