The highest electron affinity among the halogens is
Halogen with highest electron affinity
Despite being in group 17, Cl (not F) has the highest electron affinity due to F's small size
The energy released due to the addition of extra electrons to the outermost orbit of a gaseous atom is called
Definition of electron affinity
Electron affinity = energy change when a gaseous atom gains an electron
Electron affinities of halogens are in the order
Order of electron affinities of halogens
Cl has highest EA; F is smaller so added electron experiences more repulsion
