The correct electronic configuration and spin-only
magnetic moment (BM) of Gd3+ (Z = 64),
respectively, are :
Solution
Gd<sup>3+</sup> (Z = 64) = [Xe] 4f<sup>7</sup>
<br><br>Magnetic moment ($\mu$) = $\sqrt {n\left( {n + 2} \right)}$ B.M
<br><br>= $\sqrt {7\left( {7 + 2} \right)}$
<br><br>= 7.9 B.M
