how to solve question no.5

Q5. The electronic configuration of gadolinium (Atomic number 64) is:

(a) [Xe]4 ƒ³ 5d⁵ 6s² (b) [Xe] 4 ƒ⁷ 5d² 6s¹

(c) [Xe] 4 ƒ⁷ 5d¹ 6s² (d) [Xe] 4ƒ⁸ 5d⁶ 6s²

Solution

Dear Student,

Electronic configuration of Gd = [Xe] 4f⁷ 5d¹ 6s²

In Gd, one electron instead goes to 5d instead of 4f. This is because 4f and 5d orbital in Gd is about the same energy level and Gd atom has a tendency to retain the configuration with a half-filled 4f level which is more stable.
