Question

The bivalent metal ion having maximum paramagnetic behaviour among the first transition series elements is :

• A. $M{n}^{2+}$
• B. $C{u}^{2+}$
• C. $S{c}^{2+}$
• D. $C{u}^{+}$

Answer 1

Answer: (A)

$M{n}^{2+}$

$M{n}^{2+}$ will have 5 unpaired electrons in its electronic configuration so it will have maximum paramagnetic behaviour.
