Use Hund’s rule to derive the electronic configuration of Ce3+ ion,

1.	Use Hund’s rule to derive the electronic configuration of Ce3+ ion, and calculate its magnetic moment on the basis of ‘spin- only’ formula.
Answer» Ce : 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² sp⁶ 4f¹ 5d¹ 6s² Ce : [Xe] 4f¹ 5d¹ 6s² Ce³⁺: {Xe} 4f¹ For Ce³⁺: Number of unpaire electrons = n = 1 µ = \(\sqrt{n(n + 2)}\) = \(\sqrt8\) = \(2\sqrt2\) = 2.828 BM.

Use Hund’s rule to derive the electronic configuration of Ce3+ ion, and calculate its magnetic moment on the basis of ‘spin- only’ formula.

Answer»

Ce : 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² sp⁶ 4f¹ 5d¹ 6s²
Ce : [Xe] 4f¹ 5d¹ 6s²
Ce³⁺: {Xe} 4f¹
For Ce³⁺:
Number of unpaire electrons = n = 1

µ = \(\sqrt{n(n + 2)}\)

= \(\sqrt8\)

= \(2\sqrt2\)

= 2.828 BM.
