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.
One is plant mineral nutrition in general and nitrogen in particular. Nitrogen metabolism is tightly linked to photosynthesis because one of the products of the assimilation of nitrogen, glutamate, is the source of chlorophyll. And the sugars that are produced by photosynthesis are used to make glutamate and other amino acids. One of the first signs of nitrogen deficiency is chlorosis, a condition in which leaves turn yellow because there is not enough nitrogen to make glutamate. Hence, there is not enough chlorophyll.
