  1. Chap 8 Naming Binary Compounds

  2. Binary Ionic Compounds • Contain 2 different elements • Name the metal first, then the nonmetal as -ide. • Use name of a metal with a fixed charge Groups 1A, 2A, 3A and Ag, Zn, and Cd Examples: NaCl sodium chloride ZnI2 zinc iodide Al2O3 aluminum oxide

  3. Learning Check N1 Complete the names of the following binary compounds: Na3N sodium ________________ KBr potassium________________ Al2O3 aluminum ________________ MgS _________________________

  4. Solution N1 Complete the names of the following binary compounds: Na3N sodium nitride KBr potassium bromide Al2O3 aluminum oxide MgS magnesium sulfide

  5. Transition Metals Most form 2 or more positive ions 1+ 2+ 1+ or 2+ 2+ or 3+ Ag+ Cd2+ Cu+,Cu2+ Fe2+, Fe3+ silver cadmium copper(I) ion iron(II) ion ion ion copper (II) ion iron(III) ion Zn2+ zinc ion

  6. Names of Variable Ions Use a roman number after the name of a metal that forms two or more ions Transition metals and the metals in groups 4A and 5A FeCl3(Fe3+) iron (III) chloride CuCl (Cu+ ) copper (I) chloride SnF4 (Sn4+) tin (IV) fluoride PbCl2 (Pb2+) lead (II) chloride Fe2S3 (Fe3+) iron (III) sulfide

  7. Learning Check N2 Name the following compounds: A. CaO 1) calcium oxide 2) calcium(I) oxide 3) calcium (II) oxide B. SnCl4 1) tin tetrachloride 2) tin(II) chloride 3) tin(IV) chloride C. Co2O3 1) cobalt oxide 2) cobalt (III) oxide 3) cobalt trioxide

  8. Solution N2 Name the following compounds: A. CaO 1) calcium oxide B. SnCl43) tin(IV) chloride C. Co2O32) cobalt (III) oxide

  9. Learning Check N3 Complete the names of the following binary compounds with variable metal ions: FeBr2 iron (_____) bromide Cu2O copper (_____) oxide SnCl4 ___(_____ ) ______________ Fe2O3 ________________________ CuS ________________________

  10. Solution N3 Complete the names of the following binary compounds with variable metal ions: FeBr2 iron ( II ) bromide Cu2O copper ( I ) oxide SnCl4tin (IV) chloride Fe2O3iron (III) oxide CuS copper (II) sulfide

  11. Naming Binary Covalent Compounds Two nonmetals • Name each element • End the last element in -ide • Add prefixes to show more than 1 atom Prefixes mon 1 penta 5 di 2 hexa 6 tri 3 tetra 4

  12. Learning Check N4 CO carbon ______oxide CO2 carbon _______________ PCl3 phosphorus _______chloride CCl4 carbon ________chloride N2O _____nitrogen _____oxide

  13. Solution N4 CO carbon monoxide CO2 carbon dioxide PCl3 phosphorus trichloride CCl4 carbon tetrachloride N2O dinitrogen monoxide

  14. Learning Check N5 A. P2O5 1) phosphorus oxide 2) phosphorus pentoxide 3) diphosphorus pentoxide B. Cl2O71) dichlorine heptoxide 2) dichlorine oxide 3) chlorine heptoxide C. Cl21) chlorine 2) dichlorine 3) dichloride

  15. Solution N5 A. P2O5 3) diphosphorus pentoxide B. Cl2O71) dichlorine heptoxide C. Cl21) chlorine

  16. Naming Ternary Compounds • Contain at least 3 elements • Name the nonmetals as a polyatomic ion • Examples: NaNO3 Sodium nitrate K2SO4 Potassium sulfate Al(HCO3)3 Aluminum bicarbonate or aluminum hydrogen carbonate

  17. Polyatomic Ions A group of atoms with an overall charge. NH4+ ammonium OH- hydroxide NO3- nitrate NO2- nitrite CO32- ______________ HCO3- hydrogen carbonate (bicarbonate)

  18. Learning Check N6 Match each set with the correct name: A.Na2CO31) magnesium sulfite MgSO32) magnesium sulfate MgSO43) sodium carbonate B. Ca(HCO3)21) calcium carbonate CaCO32) calcium phosphate Ca3(PO4)2 3) calcium bicarbonate

  19. Solution N6 A.Na2CO33) sodium carbonate MgSO31) magnesium sulfite MgSO42) magnesium sulfate B. Ca(HCO3)23) calcium bicarbonate CaCO31) calcium carbonate Ca3(PO4)2 2) calcium phosphate

  20. Learning Check N7 A. aluminum nitrate 1) AlNO3 2) Al(NO)3 3) Al(NO3)3 B. copper(II) nitrate 1) CuNO3 2) Cu(NO3)2 3) Cu2(NO3) C. Iron (III) hydroxide 1) FeOH 2) Fe3OH 3) Fe(OH)3 D. Tin(IV) hydroxide 1) Sn(OH)4 2) Sn(OH)2 3) Sn4(OH)

  21. Solution N7 A. aluminum nitrate 3) Al(NO3)3 B. copper(II) nitrate 2) Cu(NO3)2 C. Iron (III) hydroxide 3) Fe(OH)3 D. Tin(IV) hydroxide 1) Sn(OH)4
