The correct electronic configuration and spin-only magnetic moment (BM) of Gd3+(Z = 64), respectively, are [Xe] 4f7 and 7.9. Explanation: The electronic configuration of 64Gd is [Xe] 4f7 5d1 6s2 and 64Gd3+ is[Xe] 4f7. The number of unpaired electrons is 7. μ = sqrt(n(n + 2))BM = sqrt(7(7 + 2)) = sqrt63 = 7.93 BM
