Question

The calculated spin only magnetic moment of $C{u}^{+}$ ion is:

• A. $0\text{BM}$
• B. $3.87\text{BM}$
• C. $5.93\text{BM}$
• D. $2.84\text{BM}$

Answer 1

The correct option is A $0\text{BM}$

$C{u}^{+}$ has no unpaired electron. Hence, its magnetic moment is zero. Its electronic configuration is $\left[Ar\right]3d^{10}4s^0$.
