The number of `d` electrons in `Fe^(2+)` (atomic number of `Fe = 26`) is not equal to that of the.A. p- electrons in Ne (Z = 10)B. s- electrons Mg (Z = 12)C. p- electrons in CI (Z = 17)D. d- electrtons in Fe (Z = 26) |

Answer» Correct Answer - C `Fe(3d^(6) 4s^(2)) rarr Fe^(2+) (3d^(6))` `Ne (1s^(2) 2s^(2) 2p^(6)), Mg (1s^(2) 2s^(2) 2p^(6) 3s^(2))` and `CI(1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(5))` Thus, Fe has six 3d electrons, `Fe^(2+)` has six 3d electrons, Ne has six 2p electrons, Mg has six s- electrons and CI has eleven p elements. |
