d) As
Work Step by Step
The metallic property increases as we move from top to bottom in a periodic table and decreases as we move from left to right.
a) Sr is present on the left side of the periodic table as compared to Sb, thus it is more metallic.
b) Bi is present down in the periodic table as compared to As, thus it is more metallic.
c) Out of Cl and O, the more metallic element cannot be determined.
d) As is more metallic than S because it is present on the left and down on the periodic table as compared to S.
