Answer:
1. Oxidation number can be thought of as the oxidation state on each atom, in an electrically charge particle, whether the particle is an atom, or a molecular or ionic compound. An exception to the neutral particle is that the oxidation number of a freely standing ion is the same as its electrons. Oxidation # of freely standing elements = 0. Oxidation # of what four elements O2, O3, P4, S8 will vary depending on what else they are bonded to.
