Account for fluorine shows only one oxidation state, but rest of the halogens shows different oxidation states. |

Answer» Electronic configuration of fluorine is 1s2 2s2 2px2 2py2 2pz2. It has only one orbital half filled and no d-orbital. The orbital cannot be on paired being highly electronegative. It shows only -1 oxidation state as it saturates its valences shell by accepting one electron. In all other halogen d-orbital are present and ns and p-orbital can be unpaired and the electrons are accommodated in d-orbitals, i.e., showing +3, +5 and +7 oxidation states. |
