In the Lewis structure of ICl4- there are total of 36 valence electrons. 10+ Pcl4+ Lewis Structure. The effect has been ascribed to the stabilisation of a 4s 2 electron pair in the elements following the 3d transition metals, caused by incomplete shielding of the nucleus lowering the energy of the 4s orbital and making it harder to promote 4s electrons. We can explain this apparent discrepancy by the hybridization of the 2s orbital and the three 2p orbitals on carbon to give a set of four . The trial structure has 32 valence electrons.
