Ionic Compounds Using the Stock Naming System. When elements have more than one charge, it is important to distinguish which charge is being used. We will do this in the way we name the ion. This tutorial explains how to use the stock naming system. A binary compound is one made of two different elements. There can be one of each element such as in CuCl or FeO. There can also be several of each element such as Fe 2O 3 or SnBr 4 . This lesson shows you how to name binary compounds from the formula when a cation of variable charge is involved. Naming Metal-Nonmetal Compounds If one of the two compounds is a metal, then the naming convention changes a bit. Using the stock method, a roman numeral is used after the metal to indicate which ion is using the charge. Examples: Ag 2 Cl 2 = silver (II) dichloride FeF 3 = iron (III) fluoride Naming Polyatomic Compounds Start studying The Stock System of Naming: Naming Ionic Compounds using Roman Numerals. Learn vocabulary, terms, and more with flashcards, games, and other study tools. With the Stock Method you must indicate which ion using the charge in roman numerals (ie: FeCl 2 Iron (II) chloride). Alternatively the common name may be used if the metal has more than one possible ion. Here use the Latin root and then add -ous for the lower charge. -ic for the higher charge. The classical method of naming ionic compounds is the use of Latin prefixes to signify ion charge and -ic or -ous as a suffix. For example: plumbum is known to be element Pb on the periodic table, as well as stannum (sn), Natrium (na), cuprum(Cu), Ferrum(Fe), Aurum(Au), Kalium(k), Argentum(Ag), wolfram(W) and Hydragyrum(Hg). The type of naming you will learn about is called the Stock system or Stock's system. It was designed by Alfred Stock (1876-1946), a German chemist and first published in 1919. In his own words, he considered the system to be "simple, clear, immediately intelligible, capable of the most general application."
1 Answer. The Stock Method of Naming. An ionic compound is named first by its cation and then by its anion. The cation has the same name as its element. If either the cation or the anion was a polyatomic ion, the polyatomic ion name is used in the name of the overall compound.
Naming Compounds 319-1 (II) name and write formulas o some common ionic an ionic compound, you can use the reverse cross-over method to determine the plumbic oxide Stock System iron (lll) chloride • The Stock System is only used The names of the two compounds with chlorine for FeCl2 and FeCl3 are ferrous There are two naming systems, the stock method and the common name. 16 Aug 2019 Let's start this quiz; it will give you the different functions of the International Union of Pure and Applied Chemistry (IUPAC) naming compounds.

Basically, the stock system uses the real name (NOT the Latin or Roman name; or whatever ancient name) of the element (and radicals), but include a Roman Numeral to indicate the oxidation state of Name each of the following compounds using the Stock system. (a) NaCl (b) FePO4 (c) FeCl2 (d) Hg2SO4 (e) CaS (f) Fe(OH)2 (g) Fe2O3 (h) Sn(NO3)2 (i) LiBr Just a reminder: this system of naming does not really have an offically accepted name, but is often called the Greek system (or method). It involves use of Greek prefixes when naming binary compounds of two nonmetals. Sometimes you will see the Stock system applied to these types of compounds. Name: _____ Naming Ionic Compounds Directions: Name the following compounds using the Stock Naming System. 1. CaCO 3 calcium carbonate_____ 2. KCl potassium chloride
