Quizplus · Accepted Answer

Ba (Barium) has the greatest metallic character among the options given. Metallic character increases down a group in the periodic table because the atomic size increases, making it easier for the outer electrons to be lost and exhibit metallic properties. Ba is below Ca and Mg in Group 2, making it more metallic than them. As and Se are non-metals.
