The example is Iron. It can have a -2 oxidation state, in a complex compound called Sodium Tetracarbonylferrate = Na2Fe(CO)4
A pure metal has the oxidation state zero.
It is a method to distinguish different ions of a metal.
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 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).
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.
No, there is no such compound
A pure metal has the oxidation state zero.
The subscript of the second ion identifies the oxidation state of the transition metal
