70) Iron and chlorine form an ionic compound whose formula is FeCl3. The anion’s name is similar to the elemental name, but the ending of the name has been removed and replaced with “ide.”. Answer to Give each 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. Name the following ionic compounds that contain polyatomic ions. But suppose you want to name the binary ionic compound CuO. Give each ionic compound an appropriate name. To find the formula of an ionic compound, first identify the cation and write down its symbol and charge. For example, Ca(NO3)2 is called calcium nitrate. 9. 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. This compound is therefore, copper (II) nitrate. Problem 8 Name five metals and five nonmetals that are very likely to form ionic compounds. The older method uses the suffixes -ous and -ic to denote the lower and higher charges, respectively. e) Strontium oxide. SnO b. Cr2S3 c. RbI d. BaBr2 For example, CuCl2 indicates a molecule where one Cu2+ cation associates with two Cl– anions to form a neutral compound. Its systematic name is copper (II) chloride, where copper’s oxidation number is indicated in parentheses. Boundless vets and curates high-quality, openly licensed content from around the Internet. 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. ,�$-ځ$�l��㾖����yH(O������/� `� d) Calcium bromide. Name the ionic compound formed by each pair of ions. Q. b. FeCl3 Q. a. CuSO 4 ____ copper (II) ... Write formulas for the following ionic compounds containing polyatomic ions. c) Aluminum sulfide. But to be considered an ion, they must carry a positive or negative charge. http://en.wikipedia.org/wiki/Naming_ionic_compounds%23Naming_simple_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. 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. The cation has the same name as its element. Learn this topic by watching Naming Ionic Compounds Concept Videos. strontium iodide. Li + and N 3− Mg 2 + and P 3− Li + and P 3− 10. For example, Cu(NO3)2 is copper (II) nitrate, because the charge of two nitrate ions (NO3−1) is 2\cdot(-1) = -2. Provide proper chemical names (spelling counts!). Salts of [FeCl4]− in … (adsbygoogle = window.adsbygoogle || []).push({}); In chemistry, an ionic compound is a chemical compound in which ions are held together by ionic bonds. a. SnO b. Cr2S3 c. RbI d. BaBr2. Give the name from the formula or the formula from the name for each of the following hydrated ionic compounds.BeCl2 • 2H2O. For cations that take on multiple charges (typically transition metals), the charge is written using Roman numerals in parentheses immediately following the element name. Answer to Give each ionic compound an appropriate name. - 13064223 0 Give each ionic compound an appropriate name. Fe 3 + and Br − Fe 2 + and Br − Au 3 + and S 2− Au + and S 2− 11. %%EOF CC BY-SA 3.0. http://en.wikipedia.org/wiki/ionic%20compound In the cases of iron and copper, the Latin names of the elements are used (ferrous/ferric, cuprous/cupric). Name the ionic compound formed by each pair of ions. Finally, combine the two ions to form an electrically neutral compound. 780 0 obj <>/Filter/FlateDecode/ID[]/Index[769 20]/Info 768 0 R/Length 76/Prev 1397859/Root 770 0 R/Size 789/Type/XRef/W[1 3 1]>>stream 788 0 obj <>stream b) Calcium fluoride. 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 Solution for Give each ionic compound an appropriate name.a. a. BaS Q. BaS b. FeCl3 c. PbI4 d. SrBr2 Name the element that forms compounds, under appropriate conditions, with every other element in the periodic table except He, Ne, and Ar. Name the following binary molecular compounds: (a) NF.

By sticking to each other, they resolve, or partially resolve, their separate charge imbalances. Stock systemA system of naming that includes using Roman numerals to indicate the charge on transition metals. Step-by-Step Solution: Step 1 of 3. Q. 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. Then, identify the anion and write down its symbol and charge. Then either give the same or chemical formula as necessary for each problem below. This system is still used, although it has been officially supplanted by the more precise, if slightly cumbersome, Stock system. Give each ionic compound an appropriate name.Cr2 S3. Solution (a) nitrogen trifluoride (b) dinitrogen tetroxide. For example, NaF is also known as sodium fluoride. Give each ionic compound an appropriate name. Each compound will be named using the systematic nomenclature including, where necessary, appropriate Greek prefixes. 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. endstream endobj startxref 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. a) Sodium iodide. 769 0 obj <> endobj 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. Ionic compounds have high melting and boiling points, and they tend to be hard and brittle.
