Which of the following most likely represent the atomic radius of a Cr atom,the ionic radius of a Cr²⁺ ion,and the ionic radius of a Cr³⁺ ion? A)128 pm for Cr,167 pm for Cr²⁺,and 193 pm for Cr³⁺ B)128 pm for Cr,147 pm for Cr²⁺,and 193 pm for Cr³⁺ C)128 pm for Cr,109 pm for Cr²⁺,and 63 pm for Cr³⁺ D)128 pm for Cr,89 pm for Cr²⁺,and 63 pm for Cr³⁺

Question

Quizplus · Accepted Answer

The atomic radius of Cr is 128 pm. When Cr loses electrons to form Cr²⁺ and Cr³⁺, the ionic radii decrease due to increased effective nuclear charge, resulting in smaller sizes: 89 pm for Cr²⁺ and 63 pm for Cr³⁺.
