Roman numerals represent numbers. They are used in chemical formulas to represent the valancy of transitional metals but as neither Sodium or Fluorine is a transitional metal there is no use for Roman numerals in the formula NaF.

The name of the HSO4 2- ion is hydrogen sulfate or bisulfate ion.
Could vary from 1 to 5 in its compounds.
The valency of an ammonium ion is 1 (positive).
The valency of potassium permanganate is +7.
The valency of beryllium is +2. Beryllium typically forms compounds in which it loses its two outer electrons to achieve a stable electron configuration.
The valency of copper in copper sulfate (CuSO4) is +2. This means that copper has a charge of +2 in this compound and it forms ionic bonds with the sulfate ion.
Valency is the combining capacity of an atom to form bonds with other atoms. Here are ten examples of elements and their corresponding valencies: hydrogren (1), oxygen (2), nitrogen (3), carbon (4), fluorine (1), sodium (1), magnesium (2), aluminum (3), phosphorus (3), chlorine (1).
The valency for nitride is -3. This means that nitrogen has a tendency to gain three electrons in order to achieve a stable electron configuration.
The valency of Cr2O7 is -6. This is because each oxygen atom has a valency of -2, giving a total valency of -14 for the seven oxygen atoms. Since the overall charge of the Cr2O7 ion is -2, the valency of the two chromium atoms must be +12 to balance out the negative charge.
