stock systems is used to name and element with more than oxidation number
example
iron (II) chloride FeCl2
When the compound starts with a transition metal
In chemistry, the system is that part in which the reaction is taking place. Everything else in the universe is considered to be the surroundings.
Cu2O
in chemistry stock system of nomenclature is used for naming compound that contain a multivalued metal (a metal can form more than one type of ions). in this system the oxidation number (the charge of ion) of metal is shown in parentheses using roman numerals
classical naming system
Anus?
In Chemistry
These compounds can alternatively be named copper(I) and copper(II) oxides; these so-called "Stock system" names seem to be preferred by most current textbooks of chemistry over the designations cuprous and cupric.
In chemistry the stock system is a special way to form compounds. It is called Sulfur Trioxide.

what is floor stock system
floor/ward stock system
Fifty years ago, when I got my chemistry degree, "cuprous nitrate" was the standard name for what is now called, using the Stock System, "copper(I) nitrate". Its formula is CuNO3.
IUPAC is supposed to govern naming in organic chemistry - the International Union of Pure and Applied Chemistry
everything is made of elements and chemistry is basically the study of chemicals
