The size of a phosphorus atom also interferes with its ability to form double bonds to other elements, such as oxygen, nitrogen, and sulfur. As a result, phosphorus tends to form compounds that contain two P-O single bonds where nitrogen would form an N=O double bond.Nitrogen forms the nitrate, NO 3 - , ion, for example, in which it has an oxidation number of +5.he chemistry of nitrogen is dominated by the ease with which nitrogen atoms form double and triple bonds. A neutral nitrogen atom contains five valence electrons: 2 s 2 2 p 3.
What is Ammonia? Ammonia is a nutrient that contains nitrogen and hydrogen. Its chemical formula is NH 3 in the un-ionized state and NH 4 + in the ionized form. Total ammonia is the sum of both NH 3 and NH 4 + . Total ammonia is what is measured analytically in water. Why is it Important? Ammonia is the preferred nitrogen-containing nutrient for plant growth. Ammonia can be converted to nitrite (NO 2 ) and nitrate (NO 3) by bacteria, and then used by plants. Nitrate and ammonia are the most common forms of nitrogen in aquatic systems.
