the roman numerals indicates its charge with that particular chemical (a lot of the chemicals in the middle of the periodic table have a different charge depending on the chemical it is paired with)
for example (just completley making this up ***not based on real numbers***)
Fe (III) O would be writen as Fe2O3
where
Fe (II) I would be writen as FeI2
hope it helps

The roman numeral stand for what ion is present. The numereal stands for its oxidation state. Iron II is Fe 2+ Iron III Fe 3+

Iron(III) nitrate, or ferric nitrate, is most commonly encountered as the nonahydrate Fe(NO3)3·9H2O. In this state it forms colourless to pale violet crystals, typical of non-hydrolysed iron(III) compounds. It is deliquescent and rapidly forms a pool of water if left in air. Therefore it is usually stored in tightly closed containers to keep it away from any trace of water or water vapour. Heating of its solution results in hydrolysis, and heating the solid hydrate decomposes it to a mixture of iron and nitrogen oxides.

iron is a variably charged metal. the roman numerals represent the charge. for example, iron (II) nitrate is Fe(NO3)2
