I think what you are talking about is the number of atoms of each element in the named compounds. This is usually written with the numbers slightly below the atomic symbol but this is impossible to do on a computer screen and improvising other ways leads to confusion. Compound #1 is Manganese Dioxide; #2 could be called DiManganese Heptoxide.

Why does zinc cadmium and silver compounds do not use roman Numerals in their names?
