Which of the following paramagnetic ions would exhibit a magnetic moment (spin only) of the order of $5 \mathrm{BM}$ ? (At. Nos. $\mathrm{Mn}=25, \mathrm{Cr}=24, \mathrm{~V}=23, \mathrm{Ti}=22$ )

• A

  $\mathrm{Mn}^{2+}$
• B

  $\mathrm{Ti}^{2+}$
• C

  $\mathrm{V}^{2+}$
• Correct answer
  D

  $\mathrm{Cr}^{2+}$

Solution

Hence $\mathrm{Cr}^{2+}$ has magnetic moment of the order of 5 B.M.

Hence, the correct answer is option: 'D'.
