Question

the least electron affinity is found in

Answer 1

The electron affinities of the noble gases have not been conclusively measured, so they may or may not have slightly negative values. Chlorinehas the highest E ea while mercury has the lowest. E ea generally increases across a period (row) in the periodic table, due to the filling of the valence shell of the atom.
