1 Compounds and Their Bonds Naming and Writing Ionic Formulas

2 Naming Ionic Compounds with Two Elements To name a compound that contains two elements, identify the cation and anion. name the cation first followed by the name of the anion.

3 Charges of Representative Elements

4 Names of Some Common Ions

5 Complete the names of the following ions. Ba 2+ Al 3+ K + _________ __________ _________ N 3  O 2  F  _________ __________ _________ P 3  S 2  Cl  _________ __________ _________ Quick Exercise

6 Ba 2+ Al 3+ K + barium aluminum potassium N 3  O 2  F  nitride oxide fluoride P 3  S 2  Cl  phosphide sulfide chloride Solution

7 Formula IonsName cation anion NaClNa + Cl - sodium chloride K 2 SK + S 2- potassium sulfide MgOMg 2+ O 2- magnesium oxide CaI 2 Ca 2+ I - calcium iodide Al 2 O 3 Al 3+ O 2- aluminum oxide Examples of Ionic Compounds with Two Elements

8 Write the names of the following compounds. 1) CaO___________ 2) KBr___________ 3) Al 2 O 3 ___________ 4) MgCl 2 ___________ Quick Exercise

9 Write the names of the following compounds: 1)CaOcalcium oxide 2)KBrpotassium bromide 3)Al 2 O 3 aluminum oxide 4)MgCl 2 magnesium chloride Solution

10 Quick Exercise Write the formulas and names for compounds of the following ions: Br − S 2− N 3− Na + Al 3+

11 Solution Br − S 2− N 3− Na + Al 3+ NaBr sodium bromide Na 2 S sodium sulfide Na 3 N sodium nitride AlBr 3 aluminum bromide Al 2 S 3 aluminum sulfide AlN aluminum nitride

12 Transition Metals form Positive Ions Most transition metals and Group 4 metals form 2 or more positive ions. Zn 2+, Ag +, and Cd 2+ form only one ion.

13 Metals that form more than One Cation The name of metals with two or more positive ions (cations) use a Roman numeral to identify ionic charge. Lead Pb 2+ lead(II) Pb 4+ lead(IV)

14 Naming Ionic Compounds with Variable Charge Metals

15 Naming Variable Charge Metals Transition metals with two different ions use a Roman numeral after the name of the metal to indicate ionic charge.

16 Naming FeCl 2 To name FeCl 2 1. Determine the charge of the cation using the charge of the anion (Cl - ). Fe ion + 2 Cl - = Fe ion + 2- = 0 Fe ion = Name the cation by the element name and add a Roman numeral in parenthesis to show its charge. Fe 2+ = iron(II) 3. Write the anion with an ide ending. FeCl 2 = iron(II) chloride

17 Naming Cr 2 O 3 To name Cr 2 O 3 1. Determine the charge of cation from the anion (O 2- ). 2 Cr ions + 3 O 2- = 0 2 Cr ions + 3(2-) = 0 2 Cr ions - 6 = 0 2 Cr ions = +6 Cr ion = 3+ = Cr Name the cation by the element name and add a Roman numeral in parenthesis to show its charge. Cr 3+ = chromium(III) 3. Write the anion with an ide ending. chromium(III) oxide = Cr 2 O 3

18 Learning Check Select the correct name for each. A. Fe 2 S 3 1) iron sulfide 2) iron(II) sulfide 3) iron(III) sulfide B. CuO 1) copper oxide 2) copper(I) oxide 3) copper(II) oxide

19 Solution Select the correct name for each. A. Fe 2 S 3 3) iron (III) sulfide Fe 3+ S 2- B. CuO 3) copper (II) oxide Cu 2+ O 2-

20 Guide to Writing Formulas from the Name

21 Writing Formulas Write a formula for potassium sulfide. 1. Identify the cation and anion. potassium = K + sulfide = S 2− 2. Balance the charges. K + S 2− K + 2(1+) + 2(1-) = K + and 1 S 2− = K 2 S

22 Writing Formulas Write a formula for iron(III) chloride. 1. Identify the cation and anion. iron (III) = Fe 3+ (III = charge of 3+) chloride = Cl − 2. Balance the charges. Fe 3+ Cl − Cl − = (3+) + 3(1-) = 0 Cl − 3. 1 Fe 3+ and 3 Cl − = FeCl 3

23 Learning Check What is the correct formula for each of the following? A. Copper(I) nitride 1) CuN2) CuN 3 3) Cu 3 N B. Lead(IV) oxide 1) PbO 2 2) PbO 3) Pb 2 O 4

24 Solution The correct formula is A. Copper (I) nitride 3) Cu 3 NNeed 3Cu + and N 3- B. Lead (IV) oxide 1) PbO 2 Need Pb 4+ and 2O 2-
