The correct order of the ionic radii of the ions is

Options

A. `Br^(-) gt Cl^(-) gt S^(2-) gt O^(2-) gt F^(-)`
B. `Br^(-) gt S^(2-) gt Cl^(-) gt O^(2-) gt F^(-)`
C. `Br^(-) gt S^(2-) gt Cl^(-) gt F^(-) gt O^(2-)`
D. none of these

Answer

B

Explanation

Radii of anions carrying same charge decrease from left to right in a period and increase down the group.
