| A species is oxidized in a reaction if it undergoes a increase in oxidation number. |
| For a given nonmetal central atom, the acid strength increases as the oxidation number of the central atom increases. |
| The oxidation number of an atom in an elemental substance is zero. |
| Owing to the reducing nature of thiols, changes in the metal oxidation number were also possible before precipitation. |
| The result of this transfer is the change of the oxidation number. |
| This novel arrangement seems to change the palladium atom's so-called oxidation state, or oxidation number. |
