Question

Element having highest electron affinity in periodic table

Answer 1

Electron affinity decreases down to the group form right to left across the periodic table.because electron are placed in higher energy level form the nucleus. this decrease form periodic table...

Answer 2

Answer:

Chlorine

It has the highest electron affinity and this is because of considerable repulsion in the tightly packed 2p subshell of Fluorine.

Explanation:

* chlorine has more electron affinity than chlorine because the size of fluorine is very very small 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.
