which element has a larger atomic radius than sulfur? chlorine cadmium fluorine oxygen
which element has a larger atomic radius than sulfur? chlorine cadmium fluorine oxygen
Answer
Explanation:
Step1: Recall atomic - radius trends
Atomic radius increases down a group and decreases across a period in the periodic table.
Step2: Analyze the position of sulfur and given elements
Sulfur (S) is in period 3, group 16. Chlorine (Cl) is in period 3, group 17, so its atomic radius is smaller than sulfur as it is to the right of sulfur in the same period. Fluorine (F) is in period 2, group 17, much smaller as it is in a higher - energy level. Oxygen (O) is in period 2, group 16, also smaller as it is in a higher - energy level. Cadmium (Cd) is in period 5, group 12. Since it is in a much lower period than sulfur, it has a larger atomic radius.
Answer:
B. cadmium
