The charges of the three are not a given value. They do not follow the charge patters of the Alkali/Alkali earth/ and other non metals have. Therefore, to know the charge, it must be given as a roman numeral in paranthesis () between the elements.

∙ 13y agoThe Roman numerals refer to the different oxidation states and valencies of the metals in the compound, for example in Iron (II) and Iron (III) oxides. It is just a convention that Roman numerals are used rather than simple numbers, it also avoidsany risk of confusion as ordinary numbers might be mistakenly assumed to be part of the chemical formula of the compound.
