Then either give the same or chemical formula as necessary for each problem below. CC BY-SA 3.0. http://en.wikipedia.org/wiki/Ionic_compound Wikipedia 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. a. BaS b. FeCl3 c. PbI4 d. SrBr2 . Each compound will be named using the systematic nomenclature including, where necessary, appropriate Greek prefixes. Name the ionic compound formed by each pair of ions. This particular resource used the following sources: http://www.boundless.com/ Writing names and formulas for ionic compounds. f) Silver chloride. Nomenclature, a collection of rules for naming things, is important in science and in many other situations.This module describes an approach that is used to name simple ionic and molecular compounds, such as NaCl, CaCO 3, and N 2 O 4.The simplest of these are binary compounds, those containing only two elements, but we will also consider how to name ionic compounds containing … This compound is therefore, copper (II) nitrate. Iron (Fe) can have more then 1 oxidation state, so the oxidation state must be specified in the name. ... 8. Usually, the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion. Its systematic name is copper (II) chloride, where copper’s oxidation number is indicated in parentheses. The anion’s name is similar to the elemental name, but the ending of the name has been removed and replaced with “ide.”. 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. Answer to Give each ionic compound an appropriate name. Names of some ionic compounds. The net charge of an ionic compound must be zero. Learn this topic by watching Naming Ionic Compounds Concept Videos. Remember that transition metals can have multiple oxidation states, so you are required BaS b. FeCl3 c. PbI4 d. SrBr2 70) Iron and chlorine form an ionic compound whose formula is FeCl3. Problem 8 Name five metals and five nonmetals that are very likely to form ionic compounds. Most cations and anions can combine to form neutral, solid compounds that are usually known as salts. In this video, we'll walk through this process for the ionic compound calcium bromide. For each of the following, determine whether the compound is ionic or covalent and write the appropriate formula for it. So it is Fe3+. For example, NaF is also known as sodium fluoride. The name of NaBr is sodium bromide and the name of SrF 2 is strontium fluoride. For example, K+1 is called  the potassium ion, just as K is called the potassium atom. (adsbygoogle = window.adsbygoogle || []).push({}); In chemistry, an ionic compound is a chemical compound in which ions are held together by ionic bonds. CC BY-SA 3.0. http://en.wikipedia.org/wiki/ionic%20compound h�b```��,y� ���� Work Session 2b: Formulas, Names, and Masses Use the information in your textbook for this work session, as well as the information on pages 4 and 5. The “ine” was removed and replaced with “ide.” To name a compound, the cation name and the anion named are added together. Formulas and Names for Ionic Compounds 1. SnO b. Cr2S3 c. RbI d. BaBr2 In naming an ionic compound, we follow the steps below: 1. Ionic bonds form instead of covalent bonds when there is a large difference in electronegativity between the ions. Give each ionic compound an appropriate name. %PDF-1.5 %���� 788 0 obj <>stream An ionic compound is named first by its cation and then by its anion. O.

Wikipedia Step-by-Step Solution: Step 1 of 3. Write a formula for the compound that forms between potassium and each polyatomic ion: a) carbonateb) phosphate c) hydrogen phosphated) acetate If either the cation or the anion was a polyatomic ion, the polyatomic ion name is used in the name of the overall compound. endstream endobj 770 0 obj <>/Metadata 86 0 R/OCProperties<>/OCGs[781 0 R]>>/Outlines 371 0 R/PageLayout/SinglePage/Pages 764 0 R/StructTreeRoot 404 0 R/Type/Catalog>> endobj 771 0 obj <>/ExtGState<>/Font<>/Properties<>/XObject<>>>/Rotate 0/StructParents 0/Tabs/S/Type/Page>> endobj 772 0 obj <>stream Binary Ionic Compounds. Sodium forms only a 1+ ion, so there is no ambiguity about the name sodium ion. Part 1: Binary Ionic Compounds Give the formula and name for the ionic compound formed between each of these metals with each of these nonmetals: Metals: sodium, magnesium, aluminum 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. The cation has the same name as its element. d) Calcium bromide. Ionic compounds have high melting and boiling points, and they tend to be hard and brittle. But to be considered an ion, they must carry a positive or negative charge. h��U�nA��>�z_FB�l��H�D���8�=�[3��=���� ���յ�Z��J�dD�V� �V��4d��(�OI�y#?�M�b�?�����})?��y9?����l`qq�n6M7�W}�}$��ل����|>�Cs+b�����*� Give the name and formula of the compound formed from the following elements: (a) cesium and bromine; (b) sulfur and barium; (c) calcium and fluorine. Since the net charge of the ionic compound must be zero, the Cu ion has a 2+ charge. Common, or trivial, names of compounds are sometimes used in informal conversations between chemists, especially older chemists. 9. Give each ionic compound an appropriate name. Give SrI2 ionic compound an appropriate name. Ionic compounds form when positive and negative ions share electrons and form an ionic bond.The strong attraction between positive and negative ions often produce crystalline solids that have high melting points. Give each ionic compound an appropriate name. Since some metallic elements form cations that have different positive charges, the names of ionic compounds derived from these elements must contain some indication of the cation charge. a. CuSO 4 ____ copper (II) ... Write formulas for the following ionic compounds containing polyatomic ions. (zV�cߌ�ա. Positive to positive and negative to negative ionic bonds do not occur. CC BY-SA 3.0. http://en.wikipedia.org/wiki/ionic%20compound, http://www.chem1.com/acad/webtext/intro/int-5.html, http://en.wikipedia.org/wiki/Naming_ionic_compounds%23Naming_simple_ionic_compounds, http://en.wikipedia.org/wiki/Ionic_compound, https://www.boundless.com/chemistry/textbooks/boundless-chemistry-textbook/, Convert between the chemical formula of an ionic compound and its name. Most cations and anions can combine to form solid compounds that are usually known as salts. e) Strontium oxide. h�bbd```b``� �����X$D2} ��� �+ To find the formula of an ionic compound, first identify the cation and write down its symbol and charge. Name the element that forms compounds, under appropriate conditions, with every other element in the periodic table except He, Ne, and Ar. Systematic names are formal names that are always used in print. 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. c) Aluminum sulfide. Solution for Give each ionic compound an appropriate name.a. a. BaS Q. 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.

Finally, combine the two ions to form an electrically neutral compound. h) Lithium oxide << Key Difference – Ionic vs Covalent Compounds Many differences can be noted between ionic and covalent compounds based on their macroscopic properties such as solubility in water, electrical conductivity, melting points and boiling points.The main reason for these differences is the difference in their bonding pattern.
