Question

Magnetic moment of ${}_{30}Z{n}^{2+}$ ion is same as :

• A. ${}_{29}C{u}^{1+}$
• B. ${}_{21}S{c}^{3+}$
• C. ${}_{28}C{u}^{4+}$
• D. both A and B

Answer 1

Answer: (D)

both A and B

Both $C{u}^{+}$ and $S{c}^{3+}$ have no unpaired electron. So, their magnetic moment is same as that of $Z{n}^{2+}$.
