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.
All ions are atoms. When the number of protons and electrons in an atom match, the charge is neutral. When there is an imbalance, the atom is an ion. Hydrogen typically has a â¦ charge of +1, whereas oxygen typically has a charge of -2. Oxygen therefore readily combines with two hydrogen atoms forming H2O, or water.
