You have to recognize the polyatomic ions within the formula. Naming Ionic Compounds. Suppose that you want to name the compound that results from the reaction of lithium and sulfur. Worked example: Finding the formula of an ionic compound. 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. Stock systemA system of naming that includes using Roman numerals to indicate the charge on transition metals. When you name ionic compounds, you write the name of the metal first and then the nonmetal. Naming Ionic Compounds In science, it is important to have a system that we can follow in naming things. The net charge of an ionic compound must be zero. Practice: Predict the charge on monatomic ions. Google Classroom Facebook Twitter. PLAY. Naming ionic compound with polyvalent ion. When naming ionic compounds, the cation retains the same name as the element. CC BY-SA 3.0. http://www.chem1.com/acad/webtext/intro/int-5.html 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. We'll learn how to name ionic compounds that have transition metals in them. Practice: Naming ionic compounds. Practice: Find the formula for ionic compounds. 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. Test. 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. They have more than one ions. For example, NaF is also known as sodium fluoride. By sticking to each other, they resolve, or partially resolve, their separate charge imbalances. Wikipedia It is also sometimes called the sodium salt of hypochlorous acid. Naming Ionic Compounds with Polyatomic Ions The process of naming ionic compounds with polyatomic ions is the same as naming binary ionic compounds. Most cations and anions can combine to form neutral, solid compounds that are usually known as salts. In the cases of iron and copper, the Latin names of the elements are used (ferrous/ferric, cuprous/cupric). The name of an ionic compound also gives you information about the oxidation numbers of the elements. Wikipedia This is the currently selected item. The -ide ending is added to the name of a monoatomic ion of an element. Identify the compound as an ionic compound first [begins with a metal and ends with nonmetal(s)]. These anions are called oxyanions. For example, Ca(NO3)2 is called calcium nitrate. Its systematic name is copper (II) chloride, where copper’s oxidation number is indicated in parentheses. Molecular compounds areelectrically neutral. Consult the periodic table of elements. These ions are named by adding the word hydrogen or dihydrogen in front of the name of the anion. Flashcards. Learn. This particular resource used the following sources: http://www.boundless.com/ 6. Name: _____ Naming Ionic Compounds Directions: Name the following compounds using the Stock Naming System. Example: FeCl3 is ferric chloride or iron(III) chloride.

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 The polyatomic ion name stays the same. Most cations and anions can combine to form solid compounds that are usually known as salts. With my strategy and step by step examples, you will be naming compounds like a pro in no time! You can use a chart to see the possible valences for the elements. 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://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. 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. The positively charged ion or cation comes before the negatively charged ion or anion. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Example: KNO2 is potassium nitrite, while KNO3 is potassium nitrate. Some of those ions are called polyatomic. When naming ionic compounds, all of the information you’ll need is on the periodic table. http://en.wikipedia.org/wiki/Naming_ionic_compounds%23Naming_simple_ionic_compounds Naming ionics with polyatomic ions. CC BY-SA 3.0. http://en.wikipedia.org/wiki/ionic%20compound 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. Naming Ionic Compounds Recall that ionic compounds consist of a positively charged cation and a negatively charged anion. Transfer of Electrons from metal to nonmetal Formation of Ions Attraction of oppositely charged ions. Forming and Naming Ionic Compounds: Forming rules for all Ionic Compounds: 1) Write the cation and its charge first (on the left). Its older name is cupric chloride. The anion’s name is similar to the elemental name, but the ending of the name has been removed and replaced with “ide.”. Ionic compounds consist of cations (positive ions) and anions (negative ions). In both systems, the name of the anion ends in -ide. Naming compounds have never been so simple! Example: The bleaching agent sodium hypochlorite is NaClO. She has taught science courses at the high school, college, and graduate levels. In all cases, ionic compound naming gives the positively charged cation first, followed by the negatively charged anion. 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. An ionic compound is named first by its cation and then by its anion. Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. The net charge of an ionic compound must be zero. Rules for Naming Ionic Compounds Containing Polyatomic Ions: Polyatomic ions are ions which consist of more than one atom. This notation is usually seen with metals since they commonly display more than one oxidation state or valence. Names and formulas of ionic compounds. 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. When naming ionic compounds, we always name the cation first with its full scientific name. Ionic compound nomenclature or naming is based on the names of the component ions. 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 Naming ionic compound with polyvalent ion. Given descriptors, diagrams. Ionic compounds are formed of a metal (cation) and a non-metal (anion). Naming Ionic Compounds 1 Naming Ionic Compounds What are the structural units that make up ionic compounds and how are they named? 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. begins with a metal and ends with two or three nonmetals Start studying Naming Ionic Compounds. Salts are simple inorganic binary ionic compounds. Naming ionic compound with polyvalent ion. Here is some tips, and tricks for naming ionic compounds. IUPAC Naming of Salts (Binary Inorganic Ionic Compounds) Introductory Chemistry Tutorial Key Concepts. Naming monatomic ions and ionic compounds. 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. STUDY. Therefore, the number of cations and anions in an ionic compound must be balanced to make an electrically neutral molecule. Why? You should know the Roman numerals for 1 (I), 2 (II), 3 (III), 4 (IV), 5 (V), and 6 (VI). The cation has the same name as its element. If the formula . This is the currently selected item. Example: The classic example is the chemical name for water, H2O, which is dihydrogen monoxide or dihydrogen oxide. 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. 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. Boundless vets and curates high-quality, openly licensed content from around the Internet. Ionic compounds have high melting and boiling points, and they tend to be hard and brittle. (adsbygoogle = window.adsbygoogle || []).push({}); In chemistry, an ionic compound is a chemical compound in which ions are held together by ionic bonds. The older method uses the suffixes -ous and -ic to denote the lower and higher charges, respectively. Nomenclature is the process of naming chemical compounds with different names so that they can be easily identified as separate chemicals. 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. For cations that take on multiple charges (typically transition metals), the charge is written using Roman numerals in parentheses immediately following the element name. Generally, there are two types of inorganic compounds that can be formed: ionic compounds and molecular compounds. Wikipedia Dihydrogen dioxide, H2O2, is more commonly called hydrogen dioxide or hydrogen peroxide. But to be considered an ion, they must carry a positive or negative charge. An ionic compound always has two parts. Mini Quiz Solution: Naming Ionic Compounds Name the compound CaCl2 Write the name of the cation first. The Roman numeral naming convention has wider appeal because many ions have more than two valences. The “ine” was removed and replaced with “ide.” To name a compound, the cation name and the anion named are added together. Chapter 7 Ionic Compound Naming (Practice Quiz) (with oxidation numbers and correct subscript latex codes) When naming ionic compounds, the cation retains the same name as the element. Since the net charge of the ionic compound must be zero, the Cu ion has a 2+ charge. You might see it as a metal, and a non-metal. Write. For example, Cu(NO3)2 is copper (II) nitrate, because the charge of two nitrate ions (NO3−1) is 2\cdot(-1) = -2. Since there are no ionic charges to balance out in molecular compounds, … An anionis a negatively charged ion. 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). 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. The hypo- and per- prefixes indicate less oxygen and more oxygen, respectively. For example, K+1 is called  the potassium ion, just as K is called the potassium atom. 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. Usually, the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion. 1. For example we … This compound is therefore, copper (II) nitrate. Ions (of either variety) may contain either a single element or more than one element. Salts are composed of two ions (binary means two): ⚛ a cation (positively charged ion) ⚛ an anion (negatively charged ion) Cations can be … Naming Mixed Ionic and Covalent - Answers Name the following compounds. A cation, which is a positively charged ion, and an anion which is negatively charged. CC BY-SA 3.0. http://en.wikipedia.org/wiki/Ionic_compound Thus, in an ionic bond, one ‘bonder’ must have a positive charge and the other a negative one. 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. Spell. “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. Then, we name the anion, cutting off the last syllable and adding the suffix -ide . See if you need prefixes. Sodium chloride, for instance, is an ionic compound containing sodium and chlorine. Remember, they may be either ionic or covalent compounds, so make sure you use the right naming method! Example: Cu3P is copper phosphide or copper(I) phosphide. This system is still used, although it has been officially supplanted by the more precise, if slightly cumbersome, Stock system. Some polyatomic anions contain oxygen. Ionic compounds are (usually) formed when a metal reacts with a nonmetal (ora polyatomic ion). 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. Gravity. Naming Compounds – Part 1 – YouTube: This video explains how to name covalent and ionic compounds. Naming Ionic Compounds Containing Transition Metals If an ionic compound contains a transition metal, use Roman numerals to denote which ion it is. For example, CuCl2 indicates a molecule where one Cu2+ cation associates with two Cl– anions to form a neutral compound. Naming Molecular Compounds Molecular compounds are named using a systematic approach of prefixes to indicate the number of each element present in the compound. 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. 1. 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. 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. Common polyatomic ions. Match. To name an ionic compound, the two involved ions are both individually named. 3) Ignoring the +, drop the number of the charge of the cation down as a subscript on the second element/compound. Polyatomic ions. Positive to positive and negative to negative ionic bonds do not occur. (When an ion consists of more than one element, we … Therefore, the number of cations and anions in an ionic compound must be balanced to make an electrically neutral molecule. maycilla_ Key Concepts: Terms in this set (20) Order the Events to describe ionic compound formation. For example, Sodium has a +1 charge and Chloride has a -1 charge, so the ionic compound would be named Sodium Chloride. 2) Write the anion and its charge second (on the right). Boundless Learning CaCO 3 calcium carbonate_____ 2. Polyatomic anions sometimes gain one or more H+ ions to form anions of a lower charge. One example is the ammonium Sulfate compound in Figure 5.7. Created by. At first you may incorrectly attempt to name every element in the formula. CC BY-SA. A cationis a positively charged ion 2. When working in chemistry, it is often convenient to write a chemical in symbols. They have more than one element. Covalent co… Covalent or molecular compounds form when elements shareelectrons in a covalent bond to form molecules. Email. There is no space between the element name and the parenthesis.
