naming ionic compounds

For example, CuCl2 indicates a molecule where one Cu2+ cation associates with two Cl– anions to form a neutral compound. Example: FeCl3 is ferric chloride or iron(III) chloride. When naming ionic compounds, the cation retains the same name as the element. For example, Cu(NO3)2 is copper (II) nitrate, because the charge of two nitrate ions (NO3−1) is 2\cdot(-1) = -2. Nomenclature is the process of naming chemical compounds with different names so that they can be easily identified as separate chemicals. Naming ionics with polyatomic ions. Naming Ionic Compounds Containing Transition Metals If an ionic compound contains a transition metal, use Roman numerals to denote which ion it is. Example: KNO2 is potassium nitrite, while KNO3 is potassium nitrate. CC BY-SA 3.0. http://en.wikipedia.org/wiki/ionic%20compound, http://www.chem1.com/acad/webtext/intro/int-5.html, http://en.wikipedia.org/wiki/Naming_ionic_compounds%23Naming_simple_ionic_compounds, http://en.wikipedia.org/wiki/Ionic_compound, https://www.boundless.com/chemistry/textbooks/boundless-chemistry-textbook/, Convert between the chemical formula of an ionic compound and its name. Dihydrogen dioxide, H2O2, is more commonly called hydrogen dioxide or hydrogen peroxide. A cationis a positively charged ion 2. Google Classroom Facebook Twitter. Polyatomic ions. Naming compounds have never been so simple! Names and formulas of ionic compounds. Naming Molecular Compounds Molecular compounds are named using a systematic approach of prefixes to indicate the number of each element present in the compound. CC BY-SA 3.0. http://en.wikipedia.org/wiki/Ionic_compound Usually, the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Because no other simpler formula is possible, there is no need to name it “calcium dibromide.” CaBr2 can be named using either the Stock method or the older, classic way of naming. Naming ionic compound with polyvalent ion. Consult the periodic table of elements. In the case where there is a series of four oxyanions, the hypo- and per- prefixes are used in conjunction with the -ite and -ate suffixes. These ions are named by adding the word hydrogen or dihydrogen in front of the name of the anion. IUPAC Naming of Salts (Binary Inorganic Ionic Compounds) Introductory Chemistry Tutorial Key Concepts. Chapter 7 Ionic Compound Naming (Practice Quiz) (with oxidation numbers and correct subscript latex codes) Spell. While there are higher oxidation numbers, they are less common. Naming Ionic Compounds Using -ous and -ic Although Roman numerals are used to denote the ionic charge of cations, it is still common to see and use the endings -ous or -ic. Ionic compounds are (usually) formed when a metal reacts with a nonmetal (ora polyatomic ion). This particular resource used the following sources: http://www.boundless.com/ maycilla_ Key Concepts: Terms in this set (20) Order the Events to describe ionic compound formation. Naming Ionic Compounds Recall that ionic compounds consist of a positively charged cation and a negatively charged anion. They have more than one element. Boundless Learning Molecular compounds areelectrically neutral. Suppose that you want to name the compound that results from the reaction of lithium and sulfur. PLAY. The polyatomic ion name stays the same. The anion is named by taking the elemental name, removing the ending, and adding “ide.” For example, F-1 is called fluoride, for the elemental name, fluorine. Mini Quiz Solution: Naming Ionic Compounds Name the compound CaCl2 Write the name of the cation first. An ionic compound always has two parts. This notation is usually seen with metals since they commonly display more than one oxidation state or valence. When an element forms two oxyanions, the one with less oxygen is given a name ending in -ite and the one with more oxygen are given a name that ends in -ate. There is no space between the element name and the parenthesis. Ionic compound nomenclature or naming is based on the names of the component ions. Positive to positive and negative to negative ionic bonds do not occur. Since some metallic elements form cations that have different positive charges, the names of ionic compounds derived from these elements must contain some indication of the cation charge. The cation is named first, followed by the anion. You first write the name of the metal, lithium, and then write the name of the nonmetal, adding an -ide ending so that sulfur becomes sulfide. An anionis a negatively charged ion. Example: Cu3P is copper phosphide or copper(I) phosphide. For example, Ca(NO3)2 is called calcium nitrate. Since the net charge of the ionic compound must be zero, the Cu ion has a 2+ charge. Remember, they may be either ionic or covalent compounds, so make sure you use the right naming method! When working in chemistry, it is often convenient to write a chemical in symbols. You can find metals on the left and central sections of the periodic table (e.g., Barium, Radium, and Lead), while you can find non-metals on the right side of the table. These endings are added to the Latin name of the element (e.g., stannous/stannic for tin) to represent the ions with lesser or greater charge, respectively. At first you may incorrectly attempt to name every element in the formula. Naming monatomic ions and ionic compounds. The anion’s name is similar to the elemental name, but the ending of the name has been removed and replaced with “ide.”. Then, we name the anion, cutting off the last syllable and adding the suffix -ide . For example, NaF is also known as sodium fluoride. 6. Learn. Created by. Worked example: Finding the formula of an ionic compound. We'll learn how to name ionic compounds that have transition metals in them. Naming Ionic Compounds. Ionic compounds have high melting and boiling points, and they tend to be hard and brittle. To name an ionic compound, the two involved ions are both individually named. Covalent co… 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. Here are the principal naming conventions for ionic compounds, along with examples to show how they are used: A Roman numeral in parentheses, followed by the name of the element, is used for elements that can form more than one positive ion. The hypo- and per- prefixes indicate less oxygen and more oxygen, respectively. Naming Ionic Compounds 1 Naming Ionic Compounds What are the structural units that make up ionic compounds and how are they named? or scenarios, students will write and name the chemical formulas of common polyatomic ions and ionic compounds containing main group or transition metals and bases. Example: The classic example is the chemical name for water, H2O, which is dihydrogen monoxide or dihydrogen oxide. Wikipedia It is also sometimes called the sodium salt of hypochlorous acid. Most cations and anions can combine to form solid compounds that are usually known as salts. Sodium chloride, for instance, is an ionic compound containing sodium and chlorine. Some polyatomic anions contain oxygen. Some of the worksheets for this concept are Naming ionic compounds practice work, Naming ionic compounds work i, Csus chemistry 1ae nomenclature work mack, Since we use different methods in naming binary covalent, Ionic compound formula writing work, Naming compounds practice work, Mixed ionic covalent naming, Rules for naming and writing compounds. For cations that take on multiple charges (typically transition metals), the charge is written using Roman numerals in parentheses immediately following the element name. The cation has the same name as its element. When naming ionic compounds, the cation retains the same name as the element.
