Romann numerals are used: (I), (II)...
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.
The oxidation state of transition metals is indicated by Roman numerals in parentheses following the metal's name. For example, iron(II) indicates an oxidation state of +2 for iron, while iron(III) indicates an oxidation state of +3.
Transition metals can have variable oxidation states, so charges are determined based on the overall charge of the compound or complex. The charge on the metal is often calculated by considering the charges on the ligands and balancing them with the overall charge on the compound. Oxidation state rules and knowledge of common oxidation states for transition metals can also help assign charges.
Roman numerals are used to indicate oxidation states.
The charge of transition metals that can have more than one charge is indicated by Roman numerals in parentheses following the metal's name. This helps to specify which oxidation state the metal is in a given compound.

Preferably in modern nomenclature, by capital "Roman numerals" within parentheses immediately following the name of a transition metal element cation in a chemical compound. For transition metal elements that have only two common cationic oxidation states, the oxidation states can alternatively be indicated by the suffix "ic" for the more positive oxidation state and "ous" for the less positive ones. Examples are "ferric" for "iron (III)" and "ferrous" for "iron (II)". If the transition metal is in an anion, the most common indication is with suffixes and prefixes, but the appended oxidation state in parentheses can also be used. Details may be different for different transition metals and should be sought in an authoritative reference source.
transition metals have variable oxidation states
Roman numerals in transition metal names indicate the oxidation state of the metal ion. This is important because transition metals can exist in multiple oxidation states, so the Roman numeral helps to specify which one is present in the compound.
To find the oxidation number of an element using the periodic table, you need to consider the group number for main group elements and the charge on transition metals. Main group elements typically have oxidation numbers equal to their group number, while transition metals can have multiple oxidation states indicated by Roman numerals in parentheses. Exceptions like oxygen (-2) and hydrogen (+1) exist, and the sum of oxidation numbers in a compound must equal zero.
