In the simpler, more modern approach, called the. Naming compounds have never been so simple! Today we often use chemical formulas, such as NaCl, C 12 H 22 O 11, and Co(NH 3) 6 (ClO 4) 3, to describe chemical compounds.But we still need unique names that unambiguously identify each compound. 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. If the anion is a single element, the suffix ide is added to the root name of the element. Ionic compound nomenclature or naming is based on the names of the component ions. Ionic compounds consist of cations (positive ions) and anions (negative ions). Key Concepts: Terms in this set (21) In the reactants there is a curvy arrow, what does the direction of the arrow indicate? Nomenclature of Ionic Compounds Ionic compounds are composed of ions. When you are constructing names for ionic compounds, you do not use “multipliers” to indicate how many cations or anions are present in the compound. Legal. Struggling at Naming Ionic Compounds? The simplest ionic compounds consist of a single type of cation associated with a single type of anion. A cationis a positively charged ion 2. There are exceptions to this simple nomenclature, however. We will begin with the nomenclature rules for ionic compounds. Thus, CaCO3 is named calcium carbonate; Na2SO4 is named sodium sulfate; (NH4)2HPO4 (a compound with two polyatomic ions) is named ammonium hydrogen phosphate; and Pb2+ paired with SO42-, PbSO4 is named lead (II) sulfate. Covalent compounds on the other hand, can be gases, liquids, or solids and the solid state may or may not be crystalline. Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. The cation retains its elemental name (e.g., iron or zinc), but the suffix of the nonmetal changes to -ide. In chemical nomenclature, the IUPAC nomenclature of inorganic chemistry is a systematic method of naming inorganic chemical compounds, as recommended by the International Union of Pure and Applied Chemistry (IUPAC). Thus, iron exists as Fe2+ and Fe3+ cations (they are referred to as “oxidation states”, and will be covered in detail in Chapter 5). 1. 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. Naming Ions. 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. , an ion’s positive charge is indicated by a roman numeral in parentheses after the element name, followed by the word ion. An anionis a negatively charged ion. Ideally, every possible organic compound should have a name from which an unambiguous structural … When you are constructing names for ionic compounds, you do not use “multipliers” to indicate how many cations or anions are present in the compound. We don’t have to specify an oxidation state for nickel, so this is nickel chloride. The reason why I wrote that three in this case is because the cobalt can take on multiple charges. Covalent or molecular compounds form when elements shareelectrons in a covalent bond to form molecules. Start studying Nomenclature of Ionic Compounds Assignment. Use the … We don’t have to specify an oxidation state for nickel, so this is nickel chloride. Molecular compounds areelectrically neutral. Created by. Ionic bonds form between two atoms that have different electronegativity values.Because the ability to attract electrons is so different between the atoms, it's like one atom donates its electron to the other atom in the chemical bond. You should know the Roman numerals for 1 (I), 2 (II), 3 (III), 4 (IV), 5 (V), and 6 (VI). You then Figure the formula based on the lowest whole number ratio of cations … Nomenclature of Ionic compounds assignment and quiz. Ionic compounds are compounds composed of ions, chargedparticles that form when an atom (or group of atoms, in the case of polyatomicions) gains or loses electrons. For example NaI is named sodium iodide; Na2S is named sodium sulfide; CaCl2 is named calcium chloride. For example NaI is named sodium iodide; Na2S is named sodium sulfide; CaCl2 is named calcium chloride. Want Chad’s General Chemistry Study Guides and Practice Quizzes/Tests? For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion. We use the Principle of Charge Neutrality, that is, for an ionic compound to be stable its chemical formula MUST BE NEUTRAL. 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. Even more naming ionic compounds. When you are naming an ionic compound containing iron, it is necessary to indicate which oxidation state the metal has. It is published in Nomenclature of Inorganic Chemistry (which is informally called the Red Book). Flashcards. There are two ways to make this distinction. 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. Use the rules for naming ionic compounds. Nomenclature of Ionic Compounds ** In the lesson (Molecules and Ions) we learned that ionic compounds are made up of cations (positive ions) and anions (negative ions). Legal. We must specify that iron is 2+ in this compound; iron (II) oxide. STUDY. Learn vocabulary, terms, and more with flashcards, games, and other study tools. For example, Mg could bond with SO 4-2, sulfate, to make MgSO 4, magnesium sulfate. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Nomenclature for these compounds is trivial; the cation is named first, followed by the anion. Thus, iron exists as Fe2+ and Fe3+ cations (they are referred to as “oxidation states”, and will be covered in detail in Chapter 5). 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. The procedure for naming ionic compounds contain polyatomic ions is identical to that described above for simple ions. The simplest ionic compounds consist of a single type of cation associated with a single type of anion. Positively charged ions are called cations and negatively charged ions are called anions. Learning Objective. Monatomic ions are formed from single atoms that have gained or lost electrons. The simplest ionic compounds consist of a single type of cation associated with a single type of anion. PLAY. An ion is an atom or molecule with an electrical charge. Ionic compounds are fairly easy to name, particularly when we're dealing with our main group elements. Untitled Document.

The periodic table is a help. For metals, the oxidation state is the same as the charge. Test. 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 … The cation Fe3+ paired with oxygen would have the formula Fe2O3 and would have the name iron (III) oxide. The chemist reading the name is assumed to have sufficient knowledge to pair the elements properly based on their common valence states. In all cases, ionic compound naming gives the positively charged cation first, followed by the negatively charged anion. That’s not very concrete. We don’t use multipliers, so this is simply lithium sulfide. If the anion is a single element, the suffix ideis added to the root name of the element. There are exceptions to this simple nomenclature, however. 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). The simplest ionic compounds consist of a single type of cation associated with a single type of anion. 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. Chromium (III) phosphate has the chemical formula CrPO 4. Watch the recordings here on Youtube!
