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.
In the same way, adding nutrients to water fertilizes water-dwelling plants. Typically, plants in water will continue to grow until something they need (sunlight, carbon dioxide, oxygen, or nutrients) runs out. In most streams and lakes, phosphorus or nitrogen limits plant growth.Adding more of the limiting nutrient, in fact, can stimulate too much plant growth, which starts a chain of events that may eventually deplete oxygen from the water and kill fish and other aquatic animals.n most streams and lakes, phosphorus or nitrogen limits plant growth.
