Among the elements listed—chlorine, cadmium, fluorine, and oxygen—cadmium has a larger atomic radius than sulfur. Here's a comparison based on atomic radius trends:
- Sulfur has an atomic radius of about 100 pm (empirical value).
- Chlorine, being in the same period as sulfur but with more protons, has a smaller atomic radius than sulfur.
- Fluorine and oxygen, both in higher periods and groups than sulfur, have smaller atomic radii than sulfur.
- Cadmium is in period 5 (lower down the periodic table), and elements lower in the periodic table generally have larger atomic radii, so cadmium's atomic radius is larger than sulfur's.
