Do you mean, for instance, Stock nomenclature? http://en.wikipedia.org/w/index.php?title=Stock_nomenclature&oldid=370239962

1. What is the stock system?

The stock system is a method of naming and organizing chemical compounds based on their chemical composition and the number of atoms of each element present in the compound.

2. How does the stock system work?

The stock system assigns a Roman numeral to indicate the oxidation state of the central atom in a compound. The Roman numeral is placed in parentheses after the name of the central atom, followed by the name of the non-metal element with an -ide ending.

3. Why is the stock system used?

The stock system is used to avoid confusion and provide a standardized way of naming compounds, especially those with transition metals that can have multiple oxidation states.

4. What are some examples of compounds named using the stock system?

Some examples include iron(III) oxide (Fe2O3), copper(II) chloride (CuCl2), and nickel(II) sulfate (NiSO4).

5. Are there any exceptions to the stock system?

Yes, there are some exceptions to the stock system, such as compounds with only one oxidation state, which are named using the traditional system (e.g. sodium chloride instead of sodium(I) chloride). Additionally, some elements have unique names in the stock system, such as iron(II) and iron(III) being named ferrous and ferric, respectively.
