EXAMPLE:: Assign a formal charge to the nitrogen in the compound shown below. 1  Nitrogen is in group five; thus, it has five valence electrons. 2  Number of non-bonding electrons: there are no non-bonding electrons, so this is zero.
Ammonium nitrate is formulated by combining anhydrous ammonia and nitric acid in a very corrosive manufacturing climate. Solution liquid fertilizers (28 to 32 percent nitrogen) are composed of one-half urea and one-half ammonium nitrate.It's pretty hard to apply a nitrogen fertilizer formulation that doesn't have natural gas in its manufacturing process.n some cases, the price has gone up 50 percent or more, but why is it increasing? The price of nitrogen fertilizers is directly related to the price of natural gas (methane). Manufacturing 1 ton of anhydrous ammonia fertilizer requires 33,500 cubic feet of natural gas.
