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.
Phosphorus, just like nitrogen, hydrogen or oxygen, is an element found in nature. Phosphorus is usually found in the form of phosphate but is used up quickly in nature because plants and animals need it to grow.Algae doesn't need much nitrogen or phosphorus to live, so when many nutrients are in the environment, the algae can grow at a very fast rate.The large amount of algal growth is called an algal bloom.wo nutrients that aquatic plants and animals need to grow are Nitrogen and Phosphorus. Nitrogen. Aquatic organisms need nitrogen to live and can find it in different sources throughout nature. There are two ways a living organism can get the nitrogen it needs:
