So, Thé ÃnSwer is -- From top to bottom down a group,electronegativity decreases. This is because atomic number increases down a group, and thus there is an increased distance between the valence electrons and nucleus, or a greater atomic radius. Importantexceptions of the above rules include the noble gases, lanthanides, and actinides.
