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.
Formal charges are charges we assign to each atom in a Lewis structure. This is not to be confused. with the net charge of an ion. For example, the nitrate ion, NO3. â has a net charge of â1. The N atom. has a formal charge of +1 and each oxygen atom that is singly-bonded to N has a formal charge of â1.
