Final answer:

Barium (Ba) has a larger atomic radius than Arsenic (As) because it is located lower on the periodic table, where atomic radii increase.

Step-by-step explanation:

The question asks which element has a larger atomic radius between arsenic (As) and barium (Ba). According to periodic trends, the atomic radius generally decreases across a period (row) and increases down a group (column). Arsenic is located in the fourth period and the p-block, while barium is located in the sixth period and the s-block of the periodic table. Therefore, barium (Ba) has a larger atomic radius because it is lower on the periodic table.
