For the second step, locate the elements on the periodic table. We will begin with the nomenclature rules for ionic compounds. Learn. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. For example NaI is named sodium iodide; Na2S is named sodium sulfide; CaCl2 is named calcium chloride. STUDY. s014891. You should know the Roman numerals for 1 (I), 2 (II), 3 (III), 4 (IV), 5 (V), and 6 (VI). After learning a few more details about the names of individual ions, you will be a step away from knowing how to name ionic compounds. Chad can help! The simplest ionic compounds consist of a single type of cation associated with a single type of anion. The chemist reading the name is assumed to have sufficient knowledge to pair the elements properly based on their common valence states. Recognizing Compounds With Ionic Bonds . The cation Fe3+ paired with oxygen would have the formula Fe2O3 and would have the name iron (III) oxide. Watch the recordings here on Youtube! For type-I ionic binary compounds, the cation (a metal in most cases) is named first, and the anion (usually a nonmetal) is named second. Thus Fe2+ in a compound with chloride would have a formula FeCl2 and would be named iron (II) chloride, with the oxidation state (the charge on the iron) appearing as a Roman numeral in parenthesis after the cation. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Ionic compounds are fairly easy to name, particularly when we're dealing with our main group elements. Some of the worksheets displayed are nomenclature practice answers naming organic compounds practice practice 8 1 give the iupac name of each of the following chemistry 1a nomenclature work nomenclature practice answers are on the last naming ionic compounds practice work document in microsoft internet explorer naming compounds work. The procedure for naming ionic compounds contain polyatomic ions is identical to that described above for simple ions. For metals, the oxidation state is the same as the charge. 1. Use the rules for naming ionic compounds. The simplest ionic compounds consist of a single type of cation associated with a single type of anion. In chemical nomenclature, the IUPAC nomenclature of organic chemistry is a method of naming organic chemical compounds as recommended by the International Union of Pure and Applied Chemistry (IUPAC). Learning Objective. The ions are oppositely charged and are held together (in the solid phase) by electrostatic attraction. There are exceptions to this simple nomenclature, however. Watch the recordings here on Youtube! A cationis a positively charged ion 2. Covalent co… It is published in Nomenclature of Inorganic Chemistry (which is informally called the Red Book). 3.4 Ionic Nomenclature. Nomenclature, a collection of rules for naming things, is important in science and in many other situations.This module describes an approach that is used to name simple ionic and molecular compounds, such as NaCl, CaCO 3, and N 2 O 4.The simplest of these are binary compounds, those containing only two elements, but we will also consider how to name ionic compounds containing … Ionic compounds without these ions are also known as salts and can be formed by acid–base reactions. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. We must specify that iron is 2+ in this compound; iron (II) oxide. Ideally, every possible organic compound should have a name from which an unambiguous structural … You then Figure the formula based on the lowest whole number ratio of cations … Hey, when we looked at other ionic compounds, I didn't have to write the charge of the cation there and the reason why the convention is to do it here, and I don't have to write in upper case there, so let me rewrite it as cobalt (III) sufide. If the anion is a single element, the suffix ide is added to the root name of the element. Thus, Fe 2+ is called the iron (II) ion, while Fe 3+ is called the iron (III) ion. Many transition metals exist as more than one type of cation. Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions. Legal. Start studying Nomenclature of Ionic Compounds Quiz. You can recognize ionic compounds because they consist of a metal bonded to a nonmetal. An ion is an atom or molecule with an electrical charge. [ "article:topic", "ionic compounds", "Nomenclature", "showtoc:no", "license:ccbysa", "transcluded:yes", "source[1]-chem-79757" ], 4.1: Compounds, Lewis Diagrams and Ionic Bonds, information contact us at info@libretexts.org, status page at https://status.libretexts.org, From the oxidation state that is given, copper is 2+, chloride is 1-; CuCl, From the oxidation state, iron is 3+, oxide is 2-; Fe. Molecular compounds areelectrically neutral. Legal. Because we only have one option for the cation charge, one option for the anion charge, we really don't have to worry about including any of that information in the name of the compound. The LibreTexts libraries are Powered by MindTouch® and are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. Naming compounds with polyatomic ions is very similar to naming binary compounds, but you must use your STAAR reference material to determine the proper name and formula for the polyatomic portion of the compound. Covalent compounds on the other hand, can be gases, liquids, or solids and the solid state may or may not be crystalline. In the simpler, more modern approach, called the. Write a correct chemical formula for each of the following ionic compounds: Write a proper chemical name for each of the following ionic compounds: Paul R.

Young, Professor of Chemistry, University of Illinois at Chicago, Wiki: AskTheNerd; PRYaskthenerd.com - pyounguic.edu; ChemistryOnline.com. So you do not need to state the number of cations and anions, you only need to state what they are (and what the charge is for cations with variable charges). For example, Mg could bond with SO 4-2, sulfate, to make MgSO 4, magnesium sulfate. Nomenclature for ionic compounds Worksheet-Answer Key Dr. Scott Beaver Page 3 of 5 Cl-I S2 O2-Br-N3-Na+ K+ Mg2+ Al3+ Exercise 2. Compounds Containing Only Monatomic Ions The name of a binary compound containing monatomic ions consists of the name of the cation (the name of the metal) followed by the name of the anion (the name of the nonmetallic element with its ending replaced by the suffix – ide). When you are naming an ionic compound containing iron, it is necessary to indicate which oxidation state the metal has. The cation retains its elemental name (e.g., iron or zinc), but the suffix of the nonmetal changes to -ide. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. We don’t use multipliers, so this is simply lithium sulfide. Ionic compounds have a [+] cation and a [-] anion. We don’t use multipliers, so this is simply lithium sulfide. The name of an ionic compound also gives you information about the oxidation numbers of the elements.
