To determine the oxidation state of a monoatomic ion, first determine the charge of the ion. The oxidation state will be the same as the charge. For example, I forms the monoatomic ion I¯; therefore, the oxidation state of the monoatomic ion for I is –1. Part A What is the oxidation number of the monoatomic ions of the following elements?

Learning Goal: To assign oxidation states to elements in monoatomic ions, polyatomic ions, and neutral compounds. An oxidation state (also called an oxidation number) is similar to a charge and allows you to keep track of electron transfer in oxidation-reduction reactions. Some guidelines for assigning oxidation states are described here: 1. The oxidation state of an atom in a free element is 0. Examples of free elements include Mg, Cl2 , and N2. 2. The oxidation state of a monoatomic ion is equal to its charge. Examples of monoatomic ions include Mg²+ and Cl-, the individual ions present in the ionic compound MgCl2 . 3. The sum of the oxidation states of all atoms is • for a neutral molecule or formula unit: zero; and • for an ion: the charge of the ion. 4. In compounds, • group 1A metals have an oxidation state of +1, and group 2A metals have an oxidation state of +2. 5. In compounds, nonmetals are assigned oxidation states according to the following hierarchical table. Entries at the top of the table have priority over entries at the bottom. Nonmetal Oxidation state fluorine -1 hydrogen +1 охудen -2 group 7A -1 group 6A -2 group 5A -3 The oxidation states of monoatomic ions To determine the oxidation state of a monoatomic ion, first determine the charge of the ion.
