Question

which element has a larger atomic radius than sulfur?
chlorine
cadmium
fluorine
oxygen

Explanation:

Atomic radius trends in the periodic table: atomic radius decreases across a period (left - to - right) and increases down a group. Sulfur (S) is in period 3, group 16. Chlorine (Cl) is in period 3, group 17, so its atomic radius is smaller than sulfur's. Fluorine (F) and oxygen (O) are in period 2, so they have smaller atomic radii than sulfur. Cadmium (Cd) is in period 5, group 12. Since it is in a lower period than sulfur, it has a larger atomic radius.

Answer:

B. cadmium
