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 equilibrium relationship shown above between non-labile or insoluble phosphorus forms and labile phosphorus is affected by many factors, such as size of the slowly available pool, soil temperatures, kind of compounds in the pool, kind and amount of clay in soil, and the pH of the soil solution.t low or acid pH, phosphorus is combined with iron and aluminum compounds. Maximum phosphorus availability occurs at a soil pH between 6.5 to 7.0. This is why one of the most important benefits of liming acid soils is improving phosphorus availability.
