1 Nomenclature 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 1, 2, 13 and Ag, Zn, and Cd Examples: NaClsodium chloride ZnI 2 zinc iodide Al 2 O 3 aluminum oxide

3 Naming Binary Compounds Complete the names of the following binary compounds: Na 3 Nsodium ________________ KBrpotassium________________ Al 2 O 3 aluminum ________________ MgS_________________________

4 Solution Complete the names of the following binary compounds: Na 3 Nsodium nitride KBrpotassium bromide Al 2 O 3 aluminum oxide MgSmagnesium sulfide

5 Transition Metals Most form 2 or more positive ions or or 3+ Ag + Cd 2+ Cu +, Cu 2+ Fe 2+, Fe 3+ silver cadmium copper(I) ion iron(II) ion ion ion copper (II) ion iron(III) ion Zn 2+ 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 14 and 15 FeCl 3 (Fe 3+ ) iron (III) chloride CuCl (Cu + ) copper (I) chloride SnF 4 (Sn 4+ ) tin (IV) fluoride PbCl 2 (Pb 2+ )lead (II) chloride Fe 2 S 3 (Fe 3+ )iron (III) sulfide

7 Naming Binary Compounds Name the following compounds: A. CaO 1) calcium oxide2) calcium(I) oxide 3) calcium (II) oxide B. SnCl 4 1) tin tetrachloride 2) tin(II) chloride 3) tin(IV) chloride C. Co 2 O 3 1) cobalt oxide 2) cobalt (III) oxide 3) cobalt trioxide

8 Solution Name the following compounds: A. CaO1) calcium oxide B. SnCl 4 3) tin(IV) chloride C.Co 2 O 3 2) cobalt (III) oxide

9 More Binary Compounds Complete the names of the following binary compounds with variable metal ions: FeBr 2 iron (_____) bromide Cu 2 Ocopper (_____) oxide SnCl 4 ___(_____ ) ______________ Fe 2 O 3 ___ (_____) ______________ CuS________________________

10 Solution Complete the names of the following binary compounds with variable metal ions: FeBr 2 iron ( II ) bromide Cu 2 Ocopper ( I ) oxide SnCl 4 tin (IV) chloride Fe 2 O 3 iron (III) oxide CuScopper (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 mon1 hexa6 di2hepta7 tri3octa8 tetra4nona9 penta5deca10

12 Naming Binary Covalent Compounds CO carbon ______oxide CO 2 carbon _______________ PCl 3 phosphorus _______chloride CCl 4 carbon ________chloride N 2 O_____nitrogen oxide

13 Solution CO carbon monoxide CO 2 carbon dioxide PCl 3 phosphorus trichloride CCl 4 carbon tetrachloride N 2 Odinitrogen oxide

14 Binary Covalent Compounds A.P 2 O 5 1) phosphorus oxide 2) phosphorus pentoxide 3) diphosphorus pentoxide B.Cl 2 O 7 1) dichlorine heptoxide 2) dichlorine oxide 3) chlorine heptoxide C. Cl 2 1) chlorine 2) dichlorine 3) dichloride

15 Solution A.P 2 O 5 3) diphosphorus pentoxide B.Cl 2 O 7 1) dichlorine heptoxide C. Cl 2 1) chlorine (element)

16 Binary Elements There are seven (7) elements which exist in nature as diatomic species. This means that two atoms combine to form a molecule. These elements are: hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine. Remember: HONClBrIF

17 Binary Acids An acid is a compound that is formed between hydrogen and a second nonmetal. Examine these two compounds: HCl and HCl (aq) These compounds are named: hydrogen chloride and hydrochloric acid.

18 Binary Acids The first compound is a typical binary compound and follows the standard binary system of nomenclature. The second compound has (aq) after the fromula which means aqueous. The compound is dissolved in water. The name for this compound is prefix = hydro (means water) add = acid (means that hydrogen is present) name = 2 nd nonmetal with –ic added
