Roman numerals are used to indicate oxidation states.
The suffis -ous is added for a lower valence and the suffix -ic for a higher valence.Examples: ferric-ferrous, cupric-cuprous.
The early vs. late transition metals differ in their oxidation states (each metal has different possible oxidation states). Electrons have a stronger attraction to the protons in the late transition metals, so the later transition metals form bonds that are harder to break. You can read more about transition metal properties from the links below.Source(s):

transition metals have variable oxidation states

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
When writing the chemical name for a compound with a transition metal, it is important to include the name of the transition metal as well as its oxidation state in Roman numerals. This helps to specify which ion of the transition metal is present in the compound. Additionally, any ligands or other elements in the compound should also be named and included in the chemical name.
