Question:

The correct increasing order of ionic radii of the following \(Ce^{3+}, La^{3+}, Pm^{3+}\) and \(Yb^{3+}\) is

Updated On: Jun 21, 2024

\(Yb^{3+} < Pm^{3+} < Ce^{3+} <La^{3+} \)
Ce\(^{3+}\) < Yb\(^{3+}\) < Pm\(^{3+}\) < La\(^{3+}\)
Yb\(^{3+}\) < Pm\(^{3+}\) < La\(^{3+}\) < Ce\(^{3+}\)
Pm\(^{3+}\) < La\(^{3+}\) < Ce\(^{3+}\) < Yb\(^{3+}\)
