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). For example we … The positively charged ion or cation comes before the negatively charged ion or anion. These anions are called oxyanions. 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 Since there are no ionic charges to balance out in molecular compounds, … There is no space between the element name and the parenthesis. Naming monatomic ions and ionic compounds. Since the net charge of the ionic compound must be zero, the Cu ion has a 2+ charge. Naming Mixed Ionic and Covalent - Answers Name the following compounds. An ionic compound always has two parts. 6. Naming Compounds – Part 1 – YouTube: This video explains how to name covalent and ionic compounds. Most cations and anions can combine to form solid compounds that are usually known as salts. IUPAC Naming of Salts (Binary Inorganic Ionic Compounds) Introductory Chemistry Tutorial Key Concepts. Match. Naming ionic compound with polyvalent ion. Example: The classic example is the chemical name for water, H2O, which is dihydrogen monoxide or dihydrogen oxide. Boundless vets and curates high-quality, openly licensed content from around the Internet. Why? When you name ionic compounds, you write the name of the metal first and then the nonmetal. 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, Ca(NO3)2 is called calcium nitrate. Then, we name the anion, cutting off the last syllable and adding the suffix -ide . 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. Flashcards. Polyatomic anions sometimes gain one or more H+ ions to form anions of a lower charge. When naming ionic compounds, we always name the cation first with its full scientific name. Name: _____ Naming Ionic Compounds Directions: Name the following compounds using the Stock Naming System. In all cases, ionic compound naming gives the positively charged cation first, followed by the negatively charged anion. Wikipedia 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. (adsbygoogle = window.adsbygoogle || []).push({}); In chemistry, an ionic compound is a chemical compound in which ions are held together by ionic bonds. Practice: Find the formula for ionic compounds. The name of an ionic compound also gives you information about the oxidation numbers of the elements. Mini Quiz Solution: Naming Ionic Compounds Name the compound CaCl2 Write the name of the cation first. Example: The bleaching agent sodium hypochlorite is NaClO. These ions are named by adding the word hydrogen or dihydrogen in front of the name of the anion. Ions (of either variety) may contain either a single element or more than one element. A cationis a positively charged ion 2. Covalent co… This notation is usually seen with metals since they commonly display more than one oxidation state or valence. Naming Ionic Compounds Containing Transition Metals If an ionic compound contains a transition metal, use Roman numerals to denote which ion it is. Wikipedia For instance, in biology, there are rules that scientists follow in naming … 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. STUDY. Learn. The hypo- and per- prefixes indicate less oxygen and more oxygen, 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. Most cations and anions can combine to form neutral, solid compounds that are usually known as salts. Stock systemA system of naming that includes using Roman numerals to indicate the charge on transition metals. 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. Review: Naming Ionic Compounds - Answers Write the formulas of the following ionic compounds (1 pt each): 1) iron (II) arsenide Fe 3 As 2 2) lead (II) sulfate PbSO 4 3) lead (IV) hydroxide Pb(OH) 4 4) copper (II) acetate Cu(C 2 H 3 O 2) 2 5) beryllium chloride BeCl 2 6) ammonium chromate (NH 4) 2 CrO 4 7) silver oxide Ag 2 O Ionic compounds consist of cations (positive ions) and anions (negative ions). http://en.wikipedia.org/wiki/Naming_ionic_compounds%23Naming_simple_ionic_compounds Suppose that you want to name the compound that results from the reaction of lithium and sulfur. When naming ionic compounds, the cation retains the same name as the element. If either the cation or the anion was a polyatomic ion, the polyatomic ion name is used in the name of the overall compound. 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. Molecular compounds areelectrically neutral. 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 Therefore, the number of cations and anions in an ionic compound must be balanced to make an electrically neutral molecule. 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. Some of those ions are called polyatomic. 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. Created by. Forming and Naming Ionic Compounds: Forming rules for all Ionic Compounds: 1) Write the cation and its charge first (on the left). Ionic compounds have high melting and boiling points, and they tend to be hard and brittle. Generally, there are two types of inorganic compounds that can be formed: ionic compounds and molecular compounds. Remember, they may be either ionic or covalent compounds, so make sure you use the right naming method! But to be considered an ion, they must carry a positive or negative charge. Consult the periodic table of elements. Naming Ionic Compounds with Polyatomic Ions The process of naming ionic compounds with polyatomic ions is the same as naming binary ionic compounds. Covalent or molecular compounds form when elements shareelectrons in a covalent bond to form molecules. They have more than one ions. Example: KNO2 is potassium nitrite, while KNO3 is potassium nitrate. Transfer of Electrons from metal to nonmetal Formation of Ions Attraction of oppositely charged ions. This system is still used, although it has been officially supplanted by the more precise, if slightly cumbersome, Stock system. An anionis a negatively charged ion. Wikipedia The cation has the same name as its element. Here is some tips, and tricks for naming ionic 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. Salts are composed of two ions (binary means two): ⚛ a cation (positively charged ion) ⚛ an anion (negatively charged ion) Cations can be … Usually, the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion. Salts are simple inorganic binary ionic compounds. 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. This particular resource used the following sources: http://www.boundless.com/ 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. Common polyatomic ions. Naming compounds have never been so simple! Its systematic name is copper (II) chloride, where copper’s oxidation number is indicated in parentheses. The cation is named first, followed by the anion. 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. For example, NaF is also known as sodium fluoride. This compound is therefore, copper (II) nitrate. You should know the Roman numerals for 1 (I), 2 (II), 3 (III), 4 (IV), 5 (V), and 6 (VI). Test. 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. Boundless Learning For example, K+1 is called  the potassium ion, just as K is called the potassium atom. Worked example: Finding the formula of an ionic compound. CC BY-SA. Example: Cu3P is copper phosphide or copper(I) phosphide. One example is the ammonium Sulfate compound in Figure 5.7. A cation, which is a positively charged ion, and an anion which is negatively charged. Write. Thus, in an ionic bond, one ‘bonder’ must have a positive charge and the other a negative one. In both systems, the name of the anion ends in -ide. If the formula . Sodium chloride, for instance, is an ionic compound containing sodium and chlorine. Its older name is cupric chloride. For example, Cu(NO3)2 is copper (II) nitrate, because the charge of two nitrate ions (NO3−1) is 2\cdot(-1) = -2. An ionic compound is named first by its cation and then by its anion. 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. You have to recognize the polyatomic ions within the formula. Google Classroom Facebook Twitter. 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. Naming Ionic Compounds. CaCO 3 calcium carbonate_____ 2. The Roman numeral naming convention has wider appeal because many ions have more than two valences. Ionic compounds are formed of a metal (cation) and a non-metal (anion). 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. In the cases of iron and copper, the Latin names of the elements are used (ferrous/ferric, cuprous/cupric). This is the currently selected item. 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. 2) Write the anion and its charge second (on the right). maycilla_ Key Concepts: Terms in this set (20) Order the Events to describe ionic compound formation. begins with a metal and ends with two or three nonmetals Ionic compound nomenclature or naming is based on the names of the component ions. 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. 4. Naming Ionic Compounds Recall that ionic compounds consist of a positively charged cation and a negatively charged anion. Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant.
