Respuesta :

Answer:

A) Ionic compounds containing variable metals should have Roman numerals

Explanation:

The correct option is;

A) Ionic compounds containing variable metals should have Roman numerals

This is because these variable metals have variable oxidation states and charges. Hence, to be able to distinguish between compounds containing the same  element but different charges, the roman numerals is used. For example;

FeCl₃ - Iron(III) Chloride

FeCl₂ -  Iron(II) Chloride
