What is the major advantage of the stock system over the old naming system? The stock system is well understood world wide. And, it allows for multivalent atoms. One advantage is that some elements have more than two common valences; therefore, the "ous" and "ic" are not sufficient to name the compounds.
Full Answer
Why do we use the stock system for naming compounds?
Naming compounds that involve transition metal cations necessitates use of the Stock system. Consider the binary ionic compound FeCl 3. To simply name this compound "iron chloride" would be incomplete, because iron is capable of forming two ions with different charges.
What is Stock nomenclature in chemistry?
Stock nomenclature for inorganic compounds is a widely used system of chemical nomenclature developed by the German chemist Alfred Stock and first published in 1919. In the "Stock system", the oxidation states of some or all of the elements in a compound are indicated in parentheses by Roman numerals.
What is the stock system and why is it used?
The Stock system allows the specification of transition metal ionic charge when naming ionic compounds. Roman numerals are used to indicate the amount of positive charge on the cation. What is the Stock system? For which group of metal ions would we use the Stock system? What does the Roman numeral stand for? Found a content error?
What do the Roman numerals in stock system mean?
In the "Stock system", the oxidation states of some or all of the elements in a compound are indicated in parentheses by Roman numerals.
Why do we use the Stock system?
The Stock system allows for the specification of transition metal ionic charge when naming ionic compounds. Roman numerals are used to indicate the amount of positive charge on the cation.
What is a major advantage of the Stock system over the old naming system?
Q. What is the major advantage of the Stock system over the old naming system? The Stock system gives the actual charge of the ion in roman numerals. The Stock system gives a clue of what the charge of the ion is by changing the end of the element name to end in -ous or -ic.
What is the Stock system of naming?
Stock system: A system of naming that includes using Roman numerals to indicate the charge on transition metals.
What is a major disadvantage of using classical names for ions?
A major disadvantage of using classical names for ions is that they do not tell you the actual charge of the ion. A few transition metals have only one ionic charge. The names of these cations do not have a Roman numeral.
What is the advantage Stock system?
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.
For which group of metal ions would we use the Stock system?
Naming compounds that involve transition metal cations necessitates the use of the Stock system.

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.
Is the Stock system for elements that can form two or more different ions?
The Stock System of Nomenclature: Some elements (mostly transition metals) form two or more cations with different charges. To distinguish these ions, the Stock system of nomenclature is used. Put it together and you get copper (II) chloride. Two or more oxyanions are formed by the same two elements.

What are the advantages and disadvantages of common names chemistry?
The disadvantage is that common names don't state the chemical formula. Advantages are that people can easily understand them.
What is one shortcoming of using common names for chemical compounds?
Most common names do not tell you about the chemical composition of a compound. Many common names indicate other physical characteristics of the compound.
What is the major advantage of the stock system over the old naming system?
And, it allows for multivalent atoms.#N#One advantage is that some elements have more than two common valences; therefore, the "ous" and "ic" are not sufficient to name the compounds. For example, Mn (OH)2, MnO2, Mn2O3. Another is that if the anion has more than one possible valence, the valence of the cation is called into question. An example is Na2O vs Na2O2.

In the "Stock system", the oxidation states of some or all of the elements in a compound are indicated in parentheses by Roman numerals.
Is there space between the end of the element name and the opening parenthesis?
Contrary to the usual English style for parentheses, there is no space between the end of the element name and the opening parenthesis: for AgF, the correct style is "silver (I) fluoride" not "silver (I) fluoride".
When was Stock's system adopted?
In his own words, he considered the system to be "simple, clear, immediately intelligible, capable of the most general application.". In 1924, a German commission recommended Stock's system be adopted with some changes.
When did stock approve Roman numerals?
In 1934, Stock approved of the Roman numerals, but felt it better to keep the hyphen and drop the parenthesis. This suggestion has not been followed, but the Stock system remains in use world-wide. How do we name compounds when the cation of variable charge is involved?
