The stock System
History- The type of naming you will learn around is called the Stock mechanism or Stock"s system. It to be designed by Alfred share (1876-1946), a German chemist and very first published in 1919. In his own words, he taken into consideration the system to be "simple, clear, automatically intelligible, capable of the most basic application."
In 1924, a German commission recommended Stock"s device be embraced with part changes. Because that example, FeCl2,which would have been called iron(2)-chloride follow to Stock"s initial idea, came to be iron(II) chloride in the modification proposal. In 1934, Stock approved of the roman inn numerals, however felt it better to store the hyphen and drop the parenthesis. This suggestion has not been followed, but the Stock system remains in use world-wide.

How carry out we surname compounds when the cation of variable charge is involved?
Some facets have an ext then one oxidation number and when naming a compound these must be identified. Romannumerals are shown after the cation in parenthesis( ) to show the oxidation number.
To recognize what the oxidation number is, you need to use the anion (negative ion) to recognize what the optimistic oxidation number is.
Below you have the right to see few of the elements with an ext than 1 oxidation number.
