Question:medium

The correct order of Radii is

Show Hint

In ions, the more positive the charge, the smaller the ionic radius.
Updated On: Jan 15, 2026
  • N < Be < B
  • F\(^{-}\) < O\(^{2-}\) < N\(^{3-}\)
  • Na < Li < K
  • Fe\(^{3+}\) < Fe\(^{2+}\) < Fe
Show Solution

The Correct Option is D

Solution and Explanation

The size of the ions depends on the nuclear charge and the number of electrons. The order from smallest to largest radius is: Fe\(^{3+}\), Fe\(^{2+}\), and then Fe.
