The correct electronic configuration and spin-only magnetic moment (BM) of ${Gd}^{3 +} (Z = 64),$ respectively, are :

Answer:

Solution:

Electronic configuration of

$_{64} Gd = [Xe] 4 F^{7} 5 d^{1} 6 s^{2}$

${}_{64}{Gd}^{3 +} = [Xe] 4 F^{7}$

No. of unpaired electron $= 7$

$μ = \sqrt{n (n + 2)} BM$

$= \sqrt{63}$

$= 7.93 BM$
