Answer 2

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