Question

Which arrangement is in the correct order of increasing radii? A) Cs < Mn²⁺ < Mn B) Ra < Li < Li⁺ C) P < P³^- < As³^- D) Cr < Cr³⁺ < Ca E) H < He⁺

Quizplus · Accepted Answer

The trend for increasing radii is from right to left and from top to bottom on the periodic table. Based on this trend, option C is the only arrangement that follows this trend. The radii increase from P to As to a larger complex ion with extra S and P orbitals. Options A, B, D, and E are not in the correct order of increasing radii according to the periodic trend.
