Quizplus · Accepted Answer

Electronegativity increases across a period from left to right and decreases down a group in the periodic table. Since Ba is in Group 2, Sc in Group 3, and C in Group 14, and considering their positions in periods, C (carbon) is the most electronegative, followed by Sc (scandium), with Ba (barium) being the least electronegative.
