Nitrogen do not form Pentahalides because of the non-availability of d-orbitals..where as Phosphorus have vacant d-orbitals to form Pentahalides.Posted by Shyam Prasad (student) on 2/10/09.n the case of Bismuth, due to inert pair effect Bi 3+ will be much more stable, so it will not form a pentahalide (removal of the s-electrons is necessary for forming the 5+ cation, and due to poor shielding by d and f-orbitals the s-electrons will be very strongly held by the nucleus.
The size of a phosphorus atom also interferes with its ability to form double bonds to other elements, such as oxygen, nitrogen, and sulfur. As a result, phosphorus tends to form compounds that contain two P-O single bonds where nitrogen would form an N=O double bond.Nitrogen forms the nitrate, NO 3 - , ion, for example, in which it has an oxidation number of +5.he chemistry of nitrogen is dominated by the ease with which nitrogen atoms form double and triple bonds. A neutral nitrogen atom contains five valence electrons: 2 s 2 2 p 3.
