which element has a larger atomic radius than sulfur?\n○ chlorine\n○ cadmium\n○ fluorine\n○ oxygen
which element has a larger atomic radius than sulfur?\n○ chlorine\n○ cadmium\n○ fluorine\n○ oxygen
Answer
Brief Explanations:
Atomic radius generally increases down a group and decreases across a period. Sulfur (S) is in period 3, group 16. Chlorine (Cl) is in period 3, group 17, so it has a smaller radius than sulfur. Fluorine (F) and oxygen (O) are in period 2, so they have smaller radii than sulfur. Cadmium (Cd) is in period 5, group 12, and has more electron - shells than sulfur, thus a larger atomic radius.
Answer:
B. cadmium
