which element has a larger atomic radius than sulfur?\no chlorine\no cadmium\no fluorine\no oxygen

Brief Explanations:

Atomic radius generally decreases across a period and increases down a group in the periodic table. Sulfur is in period 3, group 16. Chlorine is in the same period (3) but to the right of sulfur, so it has a smaller atomic - radius. Fluorine and oxygen are in period 2, so they have smaller atomic radii than sulfur. Cadmium is in period 5, group 12. Elements in lower periods have larger atomic radii due to more electron shells. So cadmium has a larger atomic radius than sulfur.

Answer:

B. cadmium
