They are used to tell you which oxidation state the particular metal has when bonding to the non-metal. This is only done when the oxidation state can be more than one value.

Do roman numerals appear in covalent compound?
No, Roman numerals are not used in covalent compounds. Roman numerals are used in the naming of ionic compounds to indicate the charge of a transition metal ion. In covalent compounds, the elements are combined through sharing of electrons and do not involve ions with specific charges.
When are Roman Numerals used in chemicals?
When naming compounds. For example, Iron (VI) Carbonate.
Why is Roman numerals used in the names of compounds that contain transition metals?
Numbers are used to indicate the valency of the metal in the compound. By convention Roman numerals are used so that the number isn't mistakenly confused with the numbers present in the formula.
In Europe do they still use Roman numerals?
No, nowadays Roman numerals are only used for things such as the regal numbers of kings and queens, for example Henry VIII for Henry the eighth. Roman numerals are also used in chemistry for the oxidation sates of compounds, such as Iron III oxide. Roman numerals are also used on clocks and watches and they also appear as dates in the credits of movies.

Why must roman numerals be used when naming certain ionic compounds?
You must use roman numerals to indicate which oxidation state the element is in when that element is in a compound.

How are oxidation states of transition metals indicated in the names of metal compounds?
Roman numerals are used to indicate oxidation states.

What are the types of chemical elements that roman numerals are used for?
It depends. Most time it uses when there is ionic compound.
What does the roman numerals mean on Iron II?
The II indicates the charge or oxidation state of iron, which in this case is 2+. Roman numerals are often used to show the oxidation states or ionic charges of metals in their compounds (which are always positive). Iron can also form the iron III ion which carries a 3+ charge.
