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.
nitrogen by itself is a diatomic molecule at STP (and pretty much in all conditions for that matter). This is so because Nitrogen has 5 valence electrons so each shares 3 electrons with the other. This gives each an unshared electron pair plus the 6 being shared between the two Nitrogen atoms.
