`Fe^(2+)` (Z = 26) has ....... electrons in 3d orbitals

d_z^2 orbital has :

(A): Fe^(+3) is more stable than that of Fe^(+2) . (R) : Fe^(+3) ion has half filled 3d orbital whereas Fe^(+2) does not.

Statement 1. Fe^(2+) ion has 24 electrons and its electronic configuration represents that of Cr (Z=24). Statement 2. All the five unpaired electrons, in the 3d sub shell give stability to the ion.

[Fe(CN)_6]^(3-) ion has ............. unpaired electrons and [Fe(H_2O)_6]^(3+) has ............. unpaired electrons.

The number of d - electrons in Fe^(2+) (Z = 26) is not equal to the number of electrons in which one of the following

The number of d-electrons in Fe^(2+) (Z=26) is not equal to the number of electrons in which one of the following ?
