Among the following which has higher electron affinity value
Fluorine
Chlorine
Bromine
Iodine
Atomic radii increases on moving down a group due to
decrease in nuclear charge
increase of metallic character
the addition of new shells in succesive periods
the increase in chemical reactivity
Across the period, electron affinity
decreases
increases
decrease and then increases
increase and then decreases
