What is the stock system for naming ionic compounds?
Define the Stock system for naming ionic compounds. Name compounds using the Stock system. Write formulas of compounds when given the Stock name. Stock system: Allows the specification of transition metal ionic charge when naming ionic compounds. .
What is the common system of naming elements?
The second system, called the common system, is not conventional but is still prevalent and used in the health sciences. This system recognizes that many metals have two common cations. The common system uses two suffixes (- ic and - ous) that are appended to the stem of the element name.
Why do we need different names for each iron ion?
Iron, for example, can form two cations, each of which, when combined with the same anion, makes a different compound with unique physical and chemical properties. Thus, we need a different name for each iron ion to distinguish Fe 2+ from Fe 3+.
What is Stock nomenclature for inorganic compounds?
Jump to navigation Jump to search. 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 are the ways of naming ions?
Ionic compounds are named by stating the cation first, followed by the anion. Positive and negative charges must balance. Some anions have multiple forms and are named accordingly with the use of roman numerals in parentheses.
What is the Stock system for naming ionic compounds?
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.

It means it's a 10 ion with a +2 charge and this is why it needs to be paired with two chlorides each with a minus 1 charge.
What is the Stock system in chemistry?

What is the stock system of naming and what is it used for?
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 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.

What is the process of naming ionic compounds with polyatomic ions?
The process of naming ionic compounds with polyatomic ions is the same as naming binary ionic compounds. The cation is named first, followed by the anion. One example is the ammonium sulfate compound in Figure 5.7. 6.
How are ionic compounds named?
Ionic compounds are named by stating the cation first, followed by the anion. Positive and negative charges must balance. Some anions have multiple forms and are named accordingly with the use of roman numerals in parentheses. Ternary compounds are composed of three or more elements.
What is binary ionic compound?
A binary ionic compound is a compound composed of a monatomic metal cation and a monatomic nonmetal anion. The metal cation is named first, followed by the nonmetal anion as illustrated in Figure 5.7. 1 for the compound BaCl 2. The word ion is dropped from both parts. Subscripts in the formula do not affect the name.
How to determine if a cation has more than one charge?
If you are given a formula for an ionic compound whose cation can have more than one possible charge, you must first determine the charge on the cation before identifying its correct name. For example, consider FeCl 2 and FeCl 3 . In the first compound, the iron ion has a 2+ charge because there are two Cl − ions in the formula (1− charge on each chloride ion). In the second compound, the iron ion has a 3+ charge, as indicated by the three Cl − ions in the formula. These are two different compounds that need two different names. By the Stock system, the names are iron (II) chloride and iron (III) chloride (Figure 5.7. 2 ).
What is the name of the monatomic cation?
The name of a monatomic cation is simply the name of the element followed by the word ion. Thus, Na + is the sodium ion, Al 3+ is the aluminum ion, Ca 2+ is the calcium ion, and so forth.
What is the second system of metals?
The second system, called the common system , is not conventional but is still prevalent and used in the health sciences. This system recognizes that many metals have two common cations. The common system uses two suffixes (- ic and - ous) that are appended to the stem of the element name.
Why does iron have a 2+ charge?
In the first compound, the iron ion has a 2+ charge because there are two Cl − ions in the formula (1− charge on each chloride ion). In the second compound, the iron ion has a 3+ charge, as indicated by the three Cl − ions in the formula. These are two different compounds that need two different names.
Why is it incomplete to name iron chloride?
To simply name this compound iron chloride would be incomplete because iron is capable of forming two ions with different charges.
What is the charge of copper ion?
Since the oxide ion is O 2-, the charges of the copper ion must be 1+ in the first formula and 2+ in the second formula. In the third formula, there is one tin ion for every two oxide ions. This means that the tin must carry a 4+ charge, making the name tin (IV) oxide.
What is stock nomenclature?
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.
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?
