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.
Chemical Characteristics. Nitrogen is inert in nature and does not react easily with other elements and compounds. Nitrogen forms five oxides of with oxygen, with oxidation number of nitrogen ranging from one to five.Important acid of nitrogen are nitric acid and nitrous acid.ppearance.
