D) Cs < Cr < C
E) C < Cs < Cr

Quizplus · Accepted Answer

Electronegativity increases across a period from left to right and decreases down a group in the periodic table. Cs is an alkali metal in the first group and has the lowest electronegativity among the three. Cr (chromium) is a transition metal and has higher electronegativity than Cs but lower than C (carbon), which is a non-metal. Therefore, the correct order is Cs < Cr < C.
