Stock system: A system of naming that includes using Roman numerals to indicate the charge on transition metals. In chemistry, an ionic compound is a chemical compound in which ions are held together by ionic bonds. Usually, the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion.
What is the stock system of name?
History- The type of naming you will learn about is called the Stock system or Stock's system. It was designed by Alfred Stock (1876-1946), a German chemist and first published in 1919. In his own words, he considered the system to be "simple, clear, immediately intelligible, capable of the most general application."

What is stock notation example?
Stock notation is the representation of oxidation number by putting a Roman numeral in parenthesis after the symbol of the metal in molecular formula. So, correct notation is NO2: Nitrogen (IV) oxide. FeCl3 is wrong because it should have been Iron (III) chloride and not Iron (II) chloride.
What is the stock system of naming compounds what are its advantages over the older system of naming cations?
The Stock system is a system of nomenclature in which different cations of the same element are assigned Roman numerals indicating their charge. Its advantage is that it gives the actual charge, whereas the older system used suffixes to indicate relative charges of the ions involved.
What is fecl3 in the stock system?
In this case, the subscript in the formula indicates that there are three chloride ions, each with a 1− charge. Therefore, the charge of the single iron ion must be 3+. The correct name of FeCl3 is iron(III) chloride, with the cation charge written as the Roman numeral.

What do Roman numerals indicate?
Roman numerals are used to indicate the amount of positive charge on the cation.
Why is it incomplete to name iron chloride?
To simply name this compound iron chloride would be incomplete because iron is capable of forming two ions with different charges.
