Question

Given below are two statements : Statement I : K > Mg > Al > B is the correct order in terms of metallic character. Statement II : Atomic radius is always greater than the ionic radius for any element. In the light of the above statements, choose the correct answer from the options given below

Accepted Answer

Statement I is true but Statement II is false. Statement I is correct because metallic character increases down a group and decreases across a period, placing potassium as the most metallic and boron as the least. Statement II is false because there are instances, particularly for certain elements, where the ionic radius can be larger than the atomic radius, especially for anions.
