Find the correct statement.
A) The radii of ions of the same charge increase across a period and decrease down a group.
B) If an element can form cations with different charge numbers, then for a given coordination number its ionic radius decreases with increasing charge number.
C) If one ion occurs in environments with different coordination numbers, then its measured radius decreases as the coordination number increases.

Question

Quizplus · Accepted Answer

The ionic radius decreases with increasing charge number because the higher positive charge pulls the electrons closer to the nucleus, reducing the size of the ion.
