|Naming Ionic Compounds using Roman number (The Stock system of Naming)|
The share System
History- The type of naming you will learn about is dubbed the Stock system or Stock"s system. It was designed by Alfred share (1876-1946), a German chemist and first published in 1919. In his very own words, he thought about the system to it is in "simple, clear, immediately intelligible, capable of the most basic application."
In 1924, a German commission recommended Stock"s mechanism be embraced with some changes. For example, FeCl2,which would have actually been named iron(2)-chloride follow to Stock"s original idea, came to be iron(II) chloride in the revised proposal. In 1934, Stock authorized of the roman inn numerals, but felt it much better to keep the hyphen and drop the parenthesis. This suggestion has actually not to be followed, but the Stock device remains in use world-wide.

How carry out we name compounds when the cation that variable fee is involved?
Some elements have an ext then one oxidation number and when specify name a compound these have to be identified. Romannumerals are presented after the cation in parenthesis( ) to suggest the oxidation number.
To determine what the oxidation number is, you must use the anion (negative ion) to identify what the confident oxidation number is.
Below you can see few of the facets with much more than 1 oxidation number.
