Question

Place the following in order of decreasing radius. Te²⁻ F⁻ O²⁻ A) F⁻ > O²⁻ > Te²⁻ B) F⁻ > Te²⁻ > O²⁻ C) Te²⁻ > O²⁻ > F⁻ D) Te²⁻ > F⁻ > O²⁻ E) O²⁻ > F⁻ > Te²⁻

Quizplus · Accepted Answer

The radius of anions increases with the addition of electrons and decreases across a period. Te²⁻ has the largest radius, followed by O²⁻, and F⁻ has the smallest.
