Question

The substances which contain atoms with unpaired electrons in their orbitals behave as paramagnetic substances. Such substances are weakly attracted by the magnetic field. The paramagnetism is expressed in terms of magnetic moment. The magnetic moment is related to the number of unpaired electrons according to the following relation.
Magnetic moment, $\mu =\sqrt{n(n+2)}BM$
Where, $n$ - number of unpaired electrons.
$BM$ stands for Bohr Magneton, a unit of magnetic moment.
Which of the following ions has the highest magnetic moment?

• A. $F{e}^{2+}$
• B. $M{n}^{2+}$
• C. $C{r}^{3+}$
• D. $V^{3+}$

Answer 1

Answer: (B)

Correct answer is (b) $M{n}^{2+}$
