SATHEE: D-And F-Block Elements Ques 401

D-And F-Block Elements Ques 401

Question: Among the following series of transition metal ions, the one where all metals ions have $3 d^{2}$ electronic configuration is

[CBSE PMT 2004]

Options:

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

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

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

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

Show Answer

Answer:

Correct Answer: B

Solution:

$T i_{22} = 3 d^{2} 4 s^{2}$ ; $T i^{2 +} = 3 d^{2}$

$V_{23} = 3 d^{3} 4 s^{2}$ ; $V^{2 +} = 3 d^{2}$

$C r_{24} = 3 d^{4} 4 s^{2}$ ; $C r^{4 +} = 3 d^{2}$

$M n_{25} = 3 d^{5} 4 s^{2}$ ; $M n^{5 +} = 3 d^{2}$
