Nomenclature for Binary Compounds I Ionic II Ionic III Covalent

Covalent Compounds Covalent cmps have covalent bonds involving electron sharing Covalent bonds form between two non metals. Type III: name more cation-like first; use prefixes to identify number of each atom.

Ionic Compounds (IC) IC have ionic bonds due to transfer of electrons and then attraction of oppositely charged ions. IC are cmps containing a metal (+; name first) and a non metal (-, name second with –ide ending), or a polyatomic ion. Type I: IC whose cation has a single common charge state. IC must be neutral. Type II: IC whose cation has more than one common charge state. Use (RN) to identify charge state. IC must be neutral

Type I Magnesium oxide MgO CaF2 calcium fluoride Na2S sodium sulfide Potassium bromide KBr BaS barium sulfide Sodium sulfite Na2SO3 (NH4)2SO4 aluminum sulfate Aluminum oxide Al2O3

Type II Copper(II) chloride CuCl2 Fe2O3 iron(III) oxide Mn(II) oxide MnO Chromium(II) phosphide Cr3P2 SnCl4 tin(IV) chloride Cobalt(III) sulfate Co2 (SO4)3 Mn2O3 manganese(III) oxide Calcium hydrogen carbonate Ca(HCO3)2

Type III Nitrogen tribromide NBr3 P4O10 tetraphosphorus decoxide Oxygen difluoride OF2 Fe2O3 iron(III) oxide Dichlorine pentoxide Cl2O5 N2F2 dinitrogen difluoride
