Question

Place the following ions in order of increasing radius. Ca²^+$\quad$ S²^- $\quad$Cl^- A)Ca²⁺ < Cl^-< S²^- B)Cl^- < Ca²⁺ < S²^- C)S²⁺ < Cl^- < Ca²⁺ D)Ca²⁺ < S²^- < Cl^- E)Cl^- < S²^- < Ca²⁺

Quizplus · Accepted Answer

The order of increasing ionic radius is Ca²⁺ < Cl^- < S^2-. Ca²⁺ has the smallest radius due to its higher positive charge, pulling electrons closer. Cl^- has a larger radius than Ca²⁺ because it has gained an electron, increasing electron-electron repulsion. S^2- has the largest radius due to gaining two electrons, further increasing repulsion and size.
