The pair of ions having same electronic configuration is__________.A. `Cr^(3+),Fe^(3+)`B. `Fe^(3+),Mn^(2+)`C. `Fe^(3+),Co^(3+)`D. `Sc^(3+),Cr^(3+)` |
|
Answer» Correct Answer - B Cr(24) : `3d^(5)4s^(1),Cr^(3+):3d^(3)` Fe(26) : `3d^(6)4s^(2),Fe^(3+):3d^(5)` Mn(25) : `3d^(5)4s^(2),Mn^(2+):3d^(5)` Co(27) : `3d^(7)4s^(2),Co^(3+):3d^(6)` Sc(21) : `3d^(1)4s^(2),Sc^(3+):3d^(0)` Thus, `Fe^(3+) and Mn^(2+)` have same electronic configuration. |
