Question

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

Explanation:

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

Answer:

B. cadmium
