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. BaBr 2. The cation has the same name as its element. Binary Ionic Compounds. Give SrI2 ionic compound an appropriate name. Following the rule above, you would name this compound copper oxide. Sodium forms only a 1+ ion, so there is no ambiguity about the name sodium ion. The name of NaBr is sodium bromide and the name of SrF 2 is strontium fluoride. Provide proper chemical names (spelling counts!).

In this case it has 3 Cl- ions with it. By sticking to each other, they resolve, or partially resolve, their separate charge imbalances. Q. e) Strontium oxide. 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 g) Cesium iodide. Fe 3 + and Br − Fe 2 + and Br − Au 3 + and S 2− Au + and S 2− 11. 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. 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 Step-by-Step Solution: Step 1 of 3. Name the element that forms compounds, under appropriate conditions, with every other element in the periodic table except He, Ne, and Ar. - 13064223 Therefore, the number of cations and anions in an ionic compound must be balanced to make an electrically neutral molecule. Since the net charge of the ionic compound must be zero, the Cu ion has a 2+ charge. In chemistry, an ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding.The compound is neutral overall, but consists of positively charged ions called cations and negatively charged ions called anions.These can be simple ions such as the sodium (Na +) and chloride (Cl −) in sodium chloride, or polyatomic species such as the … An ionic compound is named first by its cation and then by its 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. CC BY-SA. Salts of [FeCl4]− in … For example, K+1 is called  the potassium ion, just as K is called the potassium atom. Most cations and anions can combine to form solid compounds that are usually known as salts. Write a formula for the ionic compound that forms between each pair of elements. a. CuSO 4 ____ copper (II) ... Write formulas for the following ionic compounds containing polyatomic ions. Problem 8 Name five metals and five nonmetals that are very likely to form 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. Name: _____ Per: _____ Directions: First quickly scan the worksheet and circle any metals (as a symbol or as a name) that is a transition metal. For cations that take on multiple charges (typically transition metals), the charge is written using Roman numerals in parentheses immediately following the element name. 70) Iron and chlorine form an ionic compound whose formula is FeCl3. Solution for Give each ionic compound an appropriate name.a. 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. When naming ionic compounds, the cation retains the same name as the element. Give each ionic compound an appropriate name. h) Lithium oxide << a. BaS b. FeCl3 c. PbI4 d. SrBr2 . Writing names and formulas for ionic compounds. 769 0 obj <> endobj Its older name is cupric 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 … Since the overall charge of an ionic compound is usually 0, then this tells us that the Fe must have a charge of 3+. Each compound will be named using the systematic nomenclature including, where necessary, appropriate Greek prefixes. Boundless Learning ,�$-ځ$�l��㾖����yH(O������/� `� Name the following ionic compounds that contain polyatomic ions. Answer to Give each ionic compound an appropriate name. strontium iodide. Give each ionic compound an appropriate name. Wikipedia The older method uses the suffixes -ous and -ic to denote the lower and higher charges, respectively. 9. b) Calcium fluoride. 0 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. 4. Answer to Give each ionic compound an appropriate name. Give each ionic compound an appropriate name.Cr2 S3. This compound is therefore, copper (II) nitrate. For each of the following, determine whether the compound is ionic or covalent and write the appropriate formula for it. To find the formula of an ionic compound, first identify the cation and write down its symbol and charge. If either the cation or the anion was a polyatomic ion, the polyatomic ion name is used in the name of the overall compound. Solution for Give each ionic compound an appropriate name.a. 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. 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 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. Spell out the full name of the compound. Usually, the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion. Boundless vets and curates high-quality, openly licensed content from around the Internet.
