Whichis morestables? Fe^(3+)or Fe^(2+) - explain . |

Answer» Solution :`FE(Z=26)"" Fe to Fe^(2+)+2e^(-)` `Fe to Fe^(3+) +3e^(-)` `Fe^(2+)` [Number of electrons 24] Electronic configuration `=[Ar]3D^(6)` `Fe^(3+)` [Number of electrons 23] Electronic configuration `=[Ar]3d^(5)` Among `Fe^(3+) and Fe^(2+), Fe^(3+)` is more stable DUE to half filled d-orbital. This can be explained by Aufbau principle. Half filled and completely filled d-orbitals are more stable than partially filled d-orbitals. So `Fe^(3+)` is more stable than `Fe^(2+)`. |
