Question

Consider the set of isoelectronic atoms and ions A^2-, B^-, C, D⁺, and E²⁺. Which arrangement of relative radii is correct? A) A^2- > B^-> C > D⁺ > E²⁺ B) E²⁺ > D⁺ > C > B^- > A^2- C) A^2- > B^- > C < D⁺ < E²⁺ D) A^2-< B^- < C > D⁺ > E²⁺ E) None of the above is correct.

Quizplus · Accepted Answer

As the number of electrons increases, the atomic radius increases. So, A^2- has the largest radius, and E²⁺ has the smallest radius.
