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.
AmmoniaAmmonia (NH3) is the most important commercial compound of nitrogen. It is produced by the Haber Process. Natural gas (methane, CH4) is reacted with steam to produce carbon dioxide and hydrogen gas (H2) in a two step process.Hydrogen gas and nitrogen gas are then reacted in the Haber Process to produce ammonia.itrogen gas (N2) makes up 78.1% of the Earths air, by volume. The atmosphere of Mars, by comparison, is only 2.6% nitrogen. From an exhaustible source in our atmosphere, nitrogen gas can be obtained by liquefaction and fractional distillation.
