Sodium forms only a 1+ ion, so there is no ambiguity about the name sodium ion. Ionic compounds have high melting and boiling points, and they tend to be hard and brittle. Ionic bonds form instead of covalent bonds when there is a large difference in electronegativity between the ions. Then, identify the anion and write down its symbol and charge. 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. Give SrI2 ionic compound an appropriate name. Usually, the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion. ���Z�����ö�䵜O�~��������BhYO���5����O�vM!u�k`�z���{״��(�N�mS�^Y��:/a�>=͛v}�b߻�^�m�U�x�G�5�? 788 0 obj <>stream Write a formula for the ionic compound that forms between each pair of elements. Give each ionic compound an appropriate name. Ionic, or saltlike, amides are strongly alkaline compounds ordinarily made by treating ammonia, an amine, or a covalent amide with a reactive metal such as sodium. Determine whether the metal in the ionic compound BaO forms only one type of ion or more than one type of ion and name the compound accordingly. 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 (adsbygoogle = window.adsbygoogle || []).push({}); In chemistry, an ionic compound is a chemical compound in which ions are held together by ionic bonds. The polyatomic ion name stays the same. Boundless vets and curates high-quality, openly licensed content from around the Internet. Give each ionic compound an appropriate name.Cr2 S3. Naming Ionic Compounds – Answer Key Give the name of the following ionic compounds: Name 1) Na 2CO 3 sodium carbonate 2) NaOH sodium hydroxide 3) MgBr 2 magnesium bromide 4) KCl potassium chloride 5) FeCl 2 iron (II) chloride 6) FeCl 3 iron (III) chloride 7) Zn(OH) 2 zinc hydroxide 8) Be 2SO 4 beryllium sulfate 9) CrF This particular resource used the following sources: http://www.boundless.com/ CC BY-SA 3.0. http://en.wikipedia.org/wiki/ionic%20compound a. BaS Q. Name the element that forms compounds, under appropriate conditions, with every other element in the periodic table except He, Ne, and Ar. 769 0 obj <> endobj In both systems, the name of the anion ends in -ide. Systematic names are formal names that are always used in print. Name the following binary molecular compounds: (a) NF. This system is still used, although it has been officially supplanted by the more precise, if slightly cumbersome, Stock system. Positive to positive and negative to negative ionic bonds do not occur. In the cases of iron and copper, the Latin names of the elements are used (ferrous/ferric, cuprous/cupric). This is a binary ionic compound. strontium iodide. Thus, in an ionic bond, one ‘bonder’ must have a positive charge and the other a negative one. 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 … O. Give each ionic compound an appropriate name. For example, NaF is also known as sodium fluoride. By sticking to each other, they resolve, or partially resolve, their separate charge imbalances. Therefore, the number of cations and anions in an ionic compound must be balanced to make an electrically neutral molecule. This compound is therefore, copper (II) nitrate. Answer to Give each ionic compound an appropriate name. b) Calcium fluoride. Li + and N 3− Mg 2 + and P 3− Li + and P 3− 10. Or provide chemical formulas using proper chemcial symbols, parentheses when needed, and numbers immediately following as subscripts, as in the following format: sodium chloride would be NaCl and aluminum sulfate [Al 2 (SO 4) 3] would be expressed as Al2(SO4)3. Boundless Learning 4. In this video, we'll walk through this process for the ionic compound calcium bromide. Wikipedia Think About It Make sure that the prefixes match the subscripts in the molecular 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 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. Its systematic name is copper (II) chloride, where copper’s oxidation number is indicated in parentheses. Name the following ionic compounds that contain polyatomic ions. Writing names and formulas for ionic compounds. CC BY-SA. f) Silver chloride. 9. (zV�cߌ�ա. BaBr 2. Solution for Give each ionic compound an appropriate name.a. Stock systemA system of naming that includes using Roman numerals to indicate the charge on transition metals. Provide proper chemical names (spelling counts!). Use both the Stock and common systems, where appropriate. To name any binary ionic compound, place the cation name first, followed by the anion name.The name of Cs 2 O, then, is cesium oxide. a. BaS b. FeCl3 c. PbI4 d. SrBr2 . Fe 3 + and Br − Fe 2 + and Br − Au 3 + and S 2− Au + and S 2− 11. For example, Ca(NO3)2 is called calcium nitrate. Name: _____ Per: _____ Directions: First quickly scan the worksheet and circle any metals (as a symbol or as a name) that is a transition metal. Q. Learn this topic by watching Naming Ionic Compounds Concept Videos. a. CuSO 4 ____ copper (II) ... Write formulas for the following ionic compounds containing polyatomic ions. The cation has the same name as its element. Solution for Give each ionic compound an appropriate name.a. For cations that take on multiple charges (typically transition metals), the charge is written using Roman numerals in parentheses immediately following the element name. Following the rule above, you would name this compound copper oxide. CC BY-SA 3.0. http://en.wikipedia.org/wiki/Ionic_compound 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. 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).
