The number of d-electrons in `Fe^(2+)`(Z=26) is not equal to the number of electrons in which one of the following ?A. p-electrons in Cl (Z=17)B. d-electrons in Fe (Z=26)C. p-electrons in Ne (Z=10)D. s-electrons in Mg (Z=12) |
|
Answer» Correct Answer - A `Fe^(+2)=3d^(6)4s^(0)` six d electrons [p-electrons in chlorine] `(1s^(2)2s^(2)2p^(6)3s^(2)3p^(5))" are = 11"` as p-electrons = 6+5=11 |
