Ionic binary and Covalent binary compounds

The Naming of Binary Compounds


-Binary compounds:

-Binary compounds are two different elements bonded together either ionically or covalently

-The ending of the name is always ide

                E.g.: NaCl = sodium chloride

                E.g.: CO2 = carbon dioxide

                E.g.: MgO = magnesium oxide


-Ionic binary compounds:

                M-NM                    -Always have a metal bonded to a nonmetal

       Metal-Nonmetal                            E.g.: Na2O = Sodium(Metal) oxide(Nonmetal)

-The metal is named normally

                                                                E.g.: MgO = magnesium oxide


                                                -The nonmetal ends in ide

                                                                E.g.: AlN = Aluminium nitride

-This is true for all group 1A(alkali metals), 2A(alkaline earth metals) and 3A metals


Covalent binary compounds:

              NM-NM          -Always have a nonmetal bonded to a nonmetal

   Nonmetal-Nonmetal                   E.g.: PF3 = Phosphorous trifluoride

                                  -You must indicate the number of atoms of each nonmetal                    

                                 -If there is only one atom if the first nonmetal then just the name of the nonmetal is used

                E.g.: PF3 = Phosphorous trifluoride

-The second nonmetal is ide

                E.g.: PF3 = Phosphorous trifluoride

               E.g.: N2O4 = Dinitrogen tetroxide

                E.g.: CO = Carbon monoxide

                E.g.: CO2 = Carbon dioxide

                                                                                                                Think of:

-The prefixes(prefices) used are:                  mono = 1

                                                                di = 2

                                                                tri = 3

                                                                tetra = 4                                 

                                                                penta = 5                                pentagon = 5 sided shape

                                                                hexa = 6                                  hexagon = 6 sided shape

                                                                septa = 7                                sept = french word for 7

                                                                octa = 8                                  octagon = 8 sided shape

                                                                nona = 9

                                                                        deca = 10                               decade = 10 years
