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.
Nitrogen is chemically less reactive. This is because of the high stability of its molecule, N2. In N2, the two nitrogen atoms form a triple bond. This triple bond has very high bond strength, which is very difficult to break.It is because of nitrogen's small size that it is able to form pÏâpÏ bonds with itself.his is because of the high stability of its molecule, N2.
