Transition metals form more than one ionic charge; Roman numerals (in parentheses) follow the ion's name. Cu2+ is copper (II) ion.
Roman numerals are used: I, II, III.
Because transition metals can assume more than one charge, the transition metal ion is named by using a Roman numeral
When naming a transition metal ion that can have more than one common ionic charge, the numerical value of charge is indicated by either (i) the charge number in capital Roman numerals within parentheses after the cation name or (ii) a distinct form of the cation name, ending in "ic" for the higher ionic charge or "ous" for the lower ionic charge. Method (i) is usually preferred now, but method (ii) was often used fifty years ago and is sometimes still used.
The transition metal with 24 electrons is chromium (Cr) and its common ion with a +3 charge is Cr3+.
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.

Oxidation state rules and knowledge of common oxidation states for transition metals can also help assign charges.
Transition metals often have more than one common ionic charge due to their ability to lose different numbers of electrons from their outer shell. This variability in charge arises from the presence of multiple oxidation states and reflects the ability of transition metals to form different types of compounds.
To determine the oxidation number of a transition metal, you can consider its overall charge and the charges of other elements in the compound. You can also use the rules based on the charge of common ligands or coordination numbers in coordination compounds. Remember that transition metals can have variable oxidation states due to their ability to lose different numbers of electrons.
oxygen H2O
Iron (Fe) and Copper (Cu) are two common transition metals.
To answer that, you'd need to tell us the indicated value.
