The dand fblock elements - Result Question 26

####26. Among the following series of transition metal ions, the one where all metal ions have $3 d^{2}$ electronic configuration is (At. nos. $T i = 22$ ; $V = 23; C r = 24; M n = 25$ )

[2004]

(a) $T i^{3 +}, V^{2 +}, C r^{3 +}, M n^{4 +}$

(b) $T i^{+}, V^{4 +}, C r^{6 +}, M n^{7 +}$

(d) $T i^{2 +}, V^{3 +}, C r^{4 +}, M n^{5 +}$

Show Answer

Solution:

(d) The electronic configuration of different species given in the option (d) are:

$\begin{aligned} T i^{2 +} : 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{2} \\ V^{3 +} : 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{2} \\ C r^{4 +} : 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{2} \\ M n^{5 +} : 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{2} \end{aligned}$
