To name an ionic compound, the two involved ions are both individually named. Naming Ionic Compounds Containing Transition Metals If an ionic compound contains a transition metal, use Roman numerals to denote which ion it is. The anion’s name is similar to the elemental name, but the ending of the name has been removed and replaced with “ide.”. This compound is therefore, copper (II) nitrate. The hypo- and per- prefixes indicate less oxygen and more oxygen, respectively. For example, Sodium has a +1 charge and Chloride has a -1 charge, so the ionic compound would be named Sodium Chloride. 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. 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. When naming ionic compounds, all of the information you’ll need is on the periodic table. When naming ionic compounds, we always name the cation first with its full scientific name. This system is still used, although it has been officially supplanted by the more precise, if slightly cumbersome, Stock system. Example: The classic example is the chemical name for water, H2O, which is dihydrogen monoxide or dihydrogen oxide. Naming Ionic Compounds Using -ous and -ic, Naming Ionic Compounds Using -ite and -ate, Naming Ionic Compounds Using hypo- and per-, Ionic Compounds Containing bi- and di- Hydrogen, Why the Formation of Ionic Compounds Is Exothermic, Double Displacement Reaction Definition and Examples, The Difference Between a Cation and an Anion, Compounds With Both Ionic and Covalent Bonds, Oxidation Definition and Example in Chemistry, Ph.D., Biomedical Sciences, University of Tennessee at Knoxville, B.A., Physics and Mathematics, Hastings College. For example, Cu(NO3)2 is copper (II) nitrate, because the charge of two nitrate ions (NO3−1) is 2\cdot(-1) = -2. Write. Salts are simple inorganic binary ionic compounds. (When an ion consists of more than one element, we … Write the formulas for the four ionic compounds that can be made by combining the cations Mg2+ and Fes+2.43 (a) (NH 4) 2 CO 3 (d) AlPO 4 (b) CaI 2 (e) AgCH 3 CO 2 Ions (of either variety) may contain either a single element or more than one element. Naming monatomic ions and ionic compounds. Naming ionic compound with polyvalent ion. Naming Ionic Compounds Recall that ionic compounds consist of a positively charged cation and a negatively charged anion. When naming ionic compounds, the cation retains the same name as the element. 2) Write the anion and its charge second (on the right). While there are higher oxidation numbers, they are less common. For example, K+1 is called  the potassium ion, just as K is called the potassium atom. 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. Identify the compound as an ionic compound first [begins with a metal and ends with nonmetal(s)]. These ions are named by adding the word hydrogen or dihydrogen in front of the name of the anion. “Calcium” The anion is an element (chlorine) Remove the –ine and add –ide “Chloride” Calcium is not a transition metal, so disregard step 3 Finally, write the name of the cation followed by the name of the anion. Positive to positive and negative to negative ionic bonds do not occur. You should know the Roman numerals for 1 (I), 2 (II), 3 (III), 4 (IV), 5 (V), and 6 (VI). 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. Flashcards. They have more than one element. The Roman numerals in fact show the oxidation number, but in simple ionic compounds this will always be the same as the metal’s ionic charge. It is also sometimes called the sodium salt of hypochlorous acid. Therefore, the number of cations and anions in an ionic compound must be balanced to make an electrically neutral molecule. Naming compounds have never been so simple! Salts are composed of two ions (binary means two): ⚛ a cation (positively charged ion) ⚛ an anion (negatively charged ion) Cations can be … The -ide ending is added to the name of a monoatomic ion of an element. Boundless Learning Ionic compounds have high melting and boiling points, and they tend to be hard and brittle. Stock systemA system of naming that includes using Roman numerals to indicate the charge on transition metals. The positively charged ion or cation comes before the negatively charged ion or anion. (adsbygoogle = window.adsbygoogle || []).push({}); In chemistry, an ionic compound is a chemical compound in which ions are held together by ionic bonds. Suppose that you want to name the compound that results from the reaction of lithium and sulfur. In all cases, ionic compound naming gives the positively charged cation first, followed by the negatively charged anion. She has taught science courses at the high school, college, and graduate levels. An ionic compound always has two parts. When naming ionic compounds, the cation retains the same name as the element. These anions are called oxyanions. Usually, the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion. The Roman numeral naming convention has wider appeal because many ions have more than two valences. Mini Quiz Solution: Naming Ionic Compounds Name the compound CaCl2 Write the name of the cation first. CC BY-SA 3.0. http://en.wikipedia.org/wiki/Ionic_compound There is no space between the element name and the parenthesis. STUDY. Polyatomic anions sometimes gain one or more H+ ions to form anions of a lower charge. Chapter 7 Ionic Compound Naming (Practice Quiz) (with oxidation numbers and correct subscript latex codes) CaCO 3 calcium carbonate_____ 2. 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. Boundless vets and curates high-quality, openly licensed content from around the Internet. Covalent co… Start studying Naming Ionic Compounds. For example, nitrate ion, NO 3-, contains one nitrogen atom and three oxygen atoms.The atoms in a polyatomic ion are usually covalently bonded to one another, and therefore stay together as a single, charged unit. An ionic compound is named first by its cation and then by its anion. An anionis a negatively charged ion. 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. Then, we name the anion, cutting off the last syllable and adding the suffix -ide . You might see it as a metal, and a non-metal. The net charge of an ionic compound must be zero. 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. Since there are no ionic charges to balance out in molecular compounds, … The name of an ionic compound also gives you information about the oxidation numbers of the elements. This is the currently selected item. 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. Its older name is cupric chloride. Its systematic name is copper (II) chloride, where copper’s oxidation number is indicated in parentheses. 1. For cations that take on multiple charges (typically transition metals), the charge is written using Roman numerals in parentheses immediately following the element name. Example: Cu3P is copper phosphide or copper(I) phosphide. Ions can be single atoms, as the sodium and chlorine in common table salt (sodium chloride), or more complex groups such as the carbonate in calcium carbonate. CC BY-SA 3.0. http://www.chem1.com/acad/webtext/intro/int-5.html CC BY-SA. begins with a metal and ends with two or three nonmetals Email. Naming Ionic Compounds with Polyatomic Ions The process of naming ionic compounds with polyatomic ions is the same as naming binary ionic compounds. Learn. Some polyatomic anions contain oxygen. Dihydrogen dioxide, H2O2, is more commonly called hydrogen dioxide or hydrogen peroxide. The older method uses the suffixes -ous and -ic to denote the lower and higher charges, respectively. This notation is usually seen with metals since they commonly display more than one oxidation state or valence. Wikipedia For example, CuCl2 indicates a molecule where one Cu2+ cation associates with two Cl– anions to form a neutral compound. 3) Ignoring the +, drop the number of the charge of the cation down as a subscript on the second element/compound. Practice: Find the formula for ionic compounds. Example: KNO2 is potassium nitrite, while KNO3 is potassium nitrate. Here is some tips, and tricks for naming ionic compounds. The cation has the same name as its element. The net charge of an ionic compound must be zero. Generally, there are two types of inorganic compounds that can be formed: ionic compounds and molecular compounds. Ionic/Covalent Compound Naming Solutions 1) Na 2 CO 3 sodium carbonate 2) P 2 O 5 diphosphorus pentoxide 3) NH 3 ammonia 4) FeSO 4 iron (II) sulfate 5) SiO 2 silicon dioxide 6) GaCl 3 gallium chloride 7) CoBr 2 cobalt (II) bromide 8) B 2 H 4 diboron tetrahydride 9) CO carbon monoxide 10) P 4 If either the cation or the anion was a polyatomic ion, the polyatomic ion name is used in the name of the overall compound. Practice: Naming ionic compounds. Ionic compounds consist of cations (positive ions) and anions (negative ions). When working in chemistry, it is often convenient to write a chemical in symbols. 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. You have to recognize the polyatomic ions within the formula. 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. Wikipedia Molecular compounds areelectrically neutral. Some of those ions are called polyatomic. 6. Created by. Polyatomic ions. This is the currently selected item. 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.

With my strategy and step by step examples, you will be naming compounds like a pro in no time! Test. 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. See if you need prefixes. Naming Ionic Compounds. Remember, they may be either ionic or covalent compounds, so make sure you use the right naming method! maycilla_ Key Concepts: Terms in this set (20) Order the Events to describe ionic compound formation. The polyatomic ion name stays the same. Example: FeCl3 is ferric chloride or iron(III) chloride. You can use a chart to see the possible valences for the elements. Spell. Most cations and anions can combine to form solid compounds that are usually known as salts. Naming Molecular Compounds Molecular compounds are named using a systematic approach of prefixes to indicate the number of each element present in the compound. Thus, in an ionic bond, one ‘bonder’ must have a positive charge and the other a negative one. Given descriptors, diagrams. If a metallic element has cations of different charges, which cation is used has to be indicated by its suffix (an older method) or by Roman numerals in parentheses after its name in writing (the Stock system). 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.

They have more than one ions. 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. For example, Ca(NO3)2 is called calcium nitrate. CC BY-SA 3.0. http://en.wikipedia.org/wiki/ionic%20compound Covalent or molecular compounds form when elements shareelectrons in a covalent bond to form molecules. Common polyatomic ions. Therefore, the number of cations and anions in an ionic compound must be balanced to make an electrically neutral molecule. For instance, in biology, there are rules that scientists follow in naming … One example is the ammonium Sulfate compound in Figure 5.7. For example, NaF is also known as sodium fluoride. It is still common to see and use the older naming convention in which the prefix bi- is used to indicate the addition of a single hydrogen ion. Example: The bleaching agent sodium hypochlorite is NaClO. At first you may incorrectly attempt to name every element in the formula. The “ine” was removed and replaced with “ide.” To name a compound, the cation name and the anion named are added together. 1. The one overriding requirement is that the resulting compound must be electrically neutral: therefore the ions Ca2+ and Br– combine only in a 1:2 ratio to form calcium bromide, CaBr2.
