It is a method to distinguish different ions of a metal.
The oxidation state of a metal is indicated in the name of a compound if and when that metal has more than one oxidation states. The oxidation state is then indicated by a Roman numeral placed in parenthesis next to the metal (Stock System).
It is a method to distinguish different ions of a metal.
The oxidation state of a metal is indicated in the name of a compound when the metal can exhibit more than one oxidation state. This is commonly seen in transition metals and some post-transition metals, where Roman numerals are used to specify the oxidation state. For example, in iron(III) chloride (FeCl₃), the Roman numeral III indicates that iron has an oxidation state of +3. In contrast, if a metal has only one oxidation state, it is not typically specified in the compound's name.
The oxidation state of a transition metal is determined by the number of electrons it has lost, gained, or shared when forming compounds. This is typically indicated in the compound's formula by using Roman numerals to denote the oxidation state, such as in iron (III) oxide (Fe₂O₃), where iron has an oxidation state of +3. To identify the oxidation state, one can analyze the overall charge of the compound and the charges of the other elements involved, allowing for a systematic determination of the metal's oxidation state.
One example of a metal with a negative oxidation state in its compound is iron in the compound FeH2, where iron has an oxidation state of -2. Another example is copper in the compound Cu2S, where copper has an oxidation state of -1.
When the metal can exist in more than one oxidation state
The oxidation state of a metal is typically indicated numerically in a compound to show the charge on the metal atom. This is important for determining the reactivity and bonding behavior of the metal within the compound.

The subscript of the second ion identifies the oxidation state of the transition metal
The oxidation state of a transition metal is determined by the number of electrons it has lost, gained, or shared when forming compounds. This is typically indicated in the compound's formula by using Roman numerals to denote the oxidation state, such as in iron (III) oxide (Fe₂O₃), where iron has an oxidation state of +3. To identify the oxidation state, one can analyze the overall charge of the compound and the charges of the other elements involved, allowing for a systematic determination of the metal's oxidation state.
The oxidation state of Mn in the compound Mn2 is +2. Each Mn atom has an oxidation state of +2, as indicated by the subscript 2 in the formula Mn2.
Roman numerals are used to indicate oxidation states.
The oxidation state of a transition metal in a compound is indicated by a Roman numeral in parentheses after the metal's name. For example, in FeCl3, iron is in the +3 oxidation state, so the compound is named iron(III) chloride. The Roman numeral helps identify the charge on the transition metal ion.
