Nomenclature Naming Binary Compounds

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

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

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

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

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

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

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.

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
