Answer to Determine the oxidation number of Cl in each of the following species.1.) Cl oxidation # = unknown (no rule applies, let x = the oxidation number of Cl) O oxidation # = (-2) (there are 4 oxygen atoms, so total oxidation number is -8) Multiply the oxidation number by the number of atoms of each element in the compound: 2 (Ba) plus 2x (Cl) plus 4(-2) (O) = 0 . For a simple (monoatomic) ion, the oxidation state is equal to the net charge on the ion. Any diatomic molecule (F2, H2, Cl2, O2etc...) has an oxidation number of 0. The atom which has been reduced will see a decrease in its charge. Ba(ClO_2)_2 d). That atom has been oxidized. The common oxidation number (state) of Chlorine is -1 in compounds and ionic solutions and 0 as diatomic chlorine. ... What is the oxidation state of Al in AlCl4-? Solve for X to find the oxidation number of chlorine: Oxidation Number: same as charge on the atom; represents the number of electrons lost or gained; an atom can have more than one form or oxidation number (ie Cl +7, Cl +5, Cl-1) 5.
