the roman numeral indicates the charge of the ion in question. Some ions have can have various charges such as Iron and Manganese
It is just a convention to use Roman Numerals, for example Ferrous III oxide, rather than Ferrous 3 oxide, probably because most of the original chemical names are Latin (Ferrous, Ferrum, Ferric all meaning Iron for example).
Chemical compounds are not named in Roman numerals!
I'm not sure if it has a name, but most call it 'naming ionic compounds with multiple ion charges'. I think that what you're looking for is the "Stock System."
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.
A Roman numeral in parentheses, followed by the name of the element, is used for elements that can form more than one positive ion. This is usually seen with metals. Although Roman numerals are used to denote the ionic charge of cations, it is still common to see and use the endings -ous or -ic. These endings are added to the Latin name of the element.
The state that has four Roman numerals in its name is Massachusetts.

Roman numerals are used to represent the charge of the cation in an ionic compound. The Roman numeral is placed in parentheses after the name of the cation to indicate its charge. For example, in Fe(NO3)2, the Fe cation has a +2 charge, so it is written as iron(II).
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.
The ionic compound BaCl2 is called barium chloride in the naming system without the use of roman numerals.
No, copper does not require Roman numerals as part of its ionic compound chemical name. Roman numerals are used to indicate the charge of transition metals with variable oxidation states in ionic compounds. Copper typically has a fixed oxidation state of +2, so Roman numerals are not necessary.
Ionic compounds are named by using the name of the cation followed by the name of the anion. The cation retains its elemental name, while the anion's name is modified by changing the ending to "-ide" for monatomic anions. Roman numerals may be used in parentheses to indicate the charge of the cation if it forms more than one type of ion.
When naming ionic compounds with variable oxidation numbers, the cation's charge is specified using Roman numerals in parentheses after the metal's name. For example, iron(II) chloride and iron(III) chloride for FeCl2 and FeCl3, respectively.

A "salt" is another name for ionic compounds
