D) Ga < Ba < Br
E) Ga < Br < Ba

Quizplus · Accepted Answer

Electronegativity generally increases from left to right across a period and decreases down a group on the periodic table. Ba is lower on the periodic table than both Br and Ga, so it has a lower electronegativity. Br is to the left of Ga, so it has a lower electronegativity. Therefore, the order of increasing electronegativity is Ba < Ga < Br.
