Most cations and anions can combine to form neutral, solid compounds that are usually known as salts. Wikipedia 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. In both systems, the name of the anion ends in -ide. Remember, they may be either ionic or covalent compounds, so make sure you use the right naming method! Therefore, the number of cations and anions in an ionic compound must be balanced to make an electrically neutral molecule. The anion’s name is similar to the elemental name, but the ending of the name has been removed and replaced with “ide.”. Its systematic name is copper (II) chloride, where copper’s oxidation number is indicated in parentheses. Stock systemA system of naming that includes using Roman numerals to indicate the charge on transition metals. Here is some tips, and tricks for naming ionic compounds. Ionic compounds consist of cations (positive ions) and anions (negative ions). begins with a metal and ends with two or three nonmetals Naming Ionic Compounds. For example, Ca(NO3)2 is called calcium nitrate. Example: FeCl3 is ferric chloride or iron(III) chloride. 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. Created by. PLAY. There is no space between the element name and the parenthesis. Naming Molecular Compounds Molecular compounds are named using a systematic approach of prefixes to indicate the number of each element present in the compound. 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. 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 net charge of an ionic compound must be zero. The cation is named first, followed by the anion. Boundless vets and curates high-quality, openly licensed content from around the Internet. Since the net charge of the ionic compound must be zero, the Cu ion has a 2+ charge. For example, CuCl2 indicates a molecule where one Cu2+ cation associates with two Cl– anions to form a neutral compound. IUPAC Naming of Salts (Binary Inorganic Ionic Compounds) Introductory Chemistry Tutorial Key Concepts. When naming ionic compounds, we always name the cation first with its full scientific name. 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. The -ide ending is added to the name of a monoatomic ion of an element. Suppose that you want to name the compound that results from the reaction of lithium and sulfur. Mini Quiz Solution: Naming Ionic Compounds Name the compound CaCl2 Write the name of the cation first. CC BY-SA. Sodium chloride, for instance, is an ionic compound containing sodium and chlorine. maycilla_ Key Concepts: Terms in this set (20) Order the Events to describe ionic compound formation. Chapter 7 Ionic Compound Naming (Practice Quiz) (with oxidation numbers and correct subscript latex codes) Names and formulas of ionic compounds. 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 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/ Flashcards. Salts are simple inorganic binary ionic compounds. An anionis a negatively charged ion. You can use a chart to see the possible valences for the elements. Naming monatomic ions and ionic compounds. Given descriptors, diagrams. 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. A cationis a positively charged ion 2. Naming Ionic Compounds 1 Naming Ionic Compounds What are the structural units that make up ionic compounds and how are they named? While there are higher oxidation numbers, they are less common. Molecular compounds areelectrically neutral. For cations that take on multiple charges (typically transition metals), the charge is written using Roman numerals in parentheses immediately following the element name. For example, Cu(NO3)2 is copper (II) nitrate, because the charge of two nitrate ions (NO3−1) is 2\cdot(-1) = -2. Naming ionic compound with polyvalent ion. The net charge of an ionic compound must be zero. Naming Compounds – Part 1 – YouTube: This video explains how to name covalent and ionic compounds. “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. Common polyatomic ions. The name of an ionic compound also gives you information about the oxidation numbers of the elements. Example: The bleaching agent sodium hypochlorite is NaClO. Naming ionic compound with polyvalent ion. Naming Mixed Ionic and Covalent - Answers Name the following compounds.

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. Gravity. 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. 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. Name: _____ Naming Ionic Compounds Directions: Name the following compounds using the Stock Naming System. 4. Covalent co… Some polyatomic anions contain oxygen. 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. Ionic compound nomenclature or naming is based on the names of the component ions. 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. An ionic compound always has two parts. Practice: Predict the charge on monatomic ions. 3) Ignoring the +, drop the number of the charge of the cation down as a subscript on the second element/compound. Transfer of Electrons from metal to nonmetal Formation of Ions Attraction of oppositely charged ions. CaCO 3 calcium carbonate_____ 2. Dihydrogen dioxide, H2O2, is more commonly called hydrogen dioxide or hydrogen peroxide. Usually, the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion. This compound is therefore, copper (II) nitrate. When you name ionic compounds, you write the name of the metal first and then the nonmetal. 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. 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. In the cases of iron and copper, the Latin names of the elements are used (ferrous/ferric, cuprous/cupric). With my strategy and step by step examples, you will be naming compounds like a pro in no time! For instance, in biology, there are rules that scientists follow in naming … This notation is usually seen with metals since they commonly display more than one oxidation state or valence. This system is still used, although it has been officially supplanted by the more precise, if slightly cumbersome, Stock system. Example: Cu3P is copper phosphide or copper(I) phosphide. Most cations and anions can combine to form solid compounds that are usually known as salts. Start studying Naming Ionic Compounds. You have to recognize the polyatomic ions within the formula. (When an ion consists of more than one element, we … The hypo- and per- prefixes indicate less oxygen and more oxygen, respectively. Consult the periodic table of elements. Nomenclature is the process of naming chemical compounds with different names so that they can be easily identified as separate chemicals. (adsbygoogle = window.adsbygoogle || []).push({}); In chemistry, an ionic compound is a chemical compound in which ions are held together by ionic bonds. Google Classroom Facebook Twitter. They have more than one ions. Naming ionics with polyatomic ions. 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. Wikipedia Example: KNO2 is potassium nitrite, while KNO3 is potassium nitrate. 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. Positive to positive and negative to negative ionic bonds do not occur. The older method uses the suffixes -ous and -ic to denote the lower and higher charges, respectively. We'll learn how to name ionic compounds that have transition metals in them. For example, NaF is also known as sodium fluoride. This is the currently selected item. When naming ionic compounds, the cation retains the same name as the element. Therefore, the number of cations and anions in an ionic compound must be balanced to make an electrically neutral molecule. An ionic compound is named first by its cation and then by its anion. Practice: Find the formula for ionic compounds. Match. CC BY-SA 3.0. http://en.wikipedia.org/wiki/ionic%20compound STUDY. Salts are composed of two ions (binary means two): ⚛ a cation (positively charged ion) ⚛ an anion (negatively charged ion) Cations can be … In all cases, ionic compound naming gives the positively charged cation first, followed by the negatively charged anion. A cation, which is a positively charged ion, and an anion which is negatively charged. Ionic compounds have high melting and boiling points, and they tend to be hard and brittle. This is the currently selected item. 2) Write the anion and its charge second (on the right). If either the cation or the anion was a polyatomic ion, the polyatomic ion name is used in the name of the overall compound. Generally, there are two types of inorganic compounds that can be formed: ionic compounds and molecular compounds. The “ine” was removed and replaced with “ide.” To name a compound, the cation name and the anion named are added together. 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. 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). To name an ionic compound, the two involved ions are both individually named. You should know the Roman numerals for 1 (I), 2 (II), 3 (III), 4 (IV), 5 (V), and 6 (VI). Polyatomic ions. 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. 6. Test. For example we … By sticking to each other, they resolve, or partially resolve, their separate charge imbalances. 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 formed of a metal (cation) and a non-metal (anion). Rules for Naming Ionic Compounds Containing Polyatomic Ions: Polyatomic ions are ions which consist of more than one atom. But to be considered an ion, they must carry a positive or negative charge. Since there are no ionic charges to balance out in molecular compounds, … See if you need prefixes. They have more than one element. Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. Some of those ions are called polyatomic. Naming ionic compound with polyvalent ion. Naming Ionic Compounds In science, it is important to have a system that we can follow in naming things. Ions (of either variety) may contain either a single element or more than one element. When working in chemistry, it is often convenient to write a chemical in symbols. Naming Ionic Compounds with Polyatomic Ions The process of naming ionic compounds with polyatomic ions is the same as naming binary ionic compounds. Wikipedia At first you may incorrectly attempt to name every element in the formula. Worked example: Finding the formula of an ionic compound. Polyatomic anions sometimes gain one or more H+ ions to form anions of a lower charge. Forming and Naming Ionic Compounds: Forming rules for all Ionic Compounds: 1) Write the cation and its charge first (on the left). Learn. The Roman numeral naming convention has wider appeal because many ions have more than two valences. The cation has the same name as its element. If the formula . Why? Spell. She has taught science courses at the high school, college, and graduate levels. 1. 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. Practice: Naming ionic compounds. For example, Sodium has a +1 charge and Chloride has a -1 charge, so the ionic compound would be named Sodium Chloride. These anions are called oxyanions. Covalent or molecular compounds form when elements shareelectrons in a covalent bond to form molecules. http://en.wikipedia.org/wiki/Naming_ionic_compounds%23Naming_simple_ionic_compounds You might see it as a metal, and a non-metal. Thus, in an ionic bond, one ‘bonder’ must have a positive charge and the other a negative one. Write. It is also sometimes called the sodium salt of hypochlorous acid. The polyatomic ion name stays the same. The positively charged ion or cation comes before the negatively charged ion or anion. 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. Naming compounds have never been so simple! Naming Ionic Compounds Recall that ionic compounds consist of a positively charged cation and a negatively charged anion. 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. Its older name is cupric chloride. 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. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Identify the compound as an ionic compound first [begins with a metal and ends with nonmetal(s)]. CC BY-SA 3.0. http://en.wikipedia.org/wiki/Ionic_compound Then, we name the anion, cutting off the last syllable and adding the suffix -ide . Boundless Learning One example is the ammonium Sulfate compound in Figure 5.7. For example, K+1 is called  the potassium ion, just as K is called the potassium atom. When naming ionic compounds, the cation retains the same name as the element. Naming Ionic Compounds Containing Transition Metals If an ionic compound contains a transition metal, use Roman numerals to denote which ion it is. When naming ionic compounds, all of the information you’ll need is on the periodic table. CC BY-SA 3.0. http://www.chem1.com/acad/webtext/intro/int-5.html 1. These ions are named by adding the word hydrogen or dihydrogen in front of the name of the anion. 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.
