Answer» Correct Answer - D `Ti^(2+) = 1 s^(2) 2 s^(2) 2 p^(6) 3 s^(2) 3 p^(6) 3 d^(2) 4 s^(0)` `V^(3+) = 1 s^(2) 2 s^(2) 2 p^(6) 3 s^(2) 3 p^(6) 3 d^(2) 4 s^(0)` `Cr^(4+) = 1 s^(2) 2 s^(2) 2 p^(6) 3 s^(2) 3 p^(6) 3 d^(2) 4 s^(0)` `Mn^(5+) = 1 s^(2) 2 s^(2) 2 p^(6) 3 s^(2) 3 p^(6) 3 d^(2) 4 s^(0)` |
