Unit 5 Page 9 Covalent Naming Worksheet Name the compound CO2 Carbon dioxide N2O Dinitrogen monoxide NI3 Nitrogen triodide As2O5 Diarsenic pentaoxide CO Carbon monoxide N2O3 Dinitrogen trioxide SiBr4 Silcon tetrabromide Cl2S7 Dichlorine heptasulfide PCl5 Phosphorus pentachloride B2Cl4 Diboron tetrachloride SF6 Sulfur hexafluoride P4O10 Tetraphosphorus decaoxide Give the formula for each compound nitrogen dioxide phosphorus trifluoride NO2 PF3 sulfur hexabromide dibromine heptaoxide SBr6 Br2O7 carbon diselenide dinitrogen tetrasulfide CSe2 N2S4 diphosphorus trioxide xenon hexafluoride P2O3 XeF6 silicon tetrachloride arsenic pentafluoride SiCl4 AsF5 1 Page 10 Practice Ionic Tin (II) Chloride PbCl2 SnCl2 Lead (II) Chloride Iron (III) Nitride Co2O3 FeN Cobalt (III) Oxide Copper (I) Bromide SnS CuBr Tin(II) Sulfide Circle the correct chemical formula for each compound below. Make sure the positive and negative charges are balanced. o calcium oxide CaO Ca2O CaO2 o magnesium fluoride MgF Mg2F MgF2 o sodium sulfide NaS Na2S NaS2 o barium nitride BaN Ba2N3 Ba3N2 Naming Acids If the compound begins with Hydrogen, it is an acid. If the acid does not contain a polyatomic ion, write the prefix hydro-, then name the second element and change the ending to –ic.’ o HCl hydrochloric acid o HBr hydrobromic acid o H2S hydrosulfuric acid Naming Acids with Polyatomic Ions The polyatomic ions you have memorized have –ate as the ending, so you name the polyatomic ion and change the ending to –ic. 2- Use sulfate (SO4 ) as the example H2SO4 is sulfuric acid 2- If the ion has one more oxygen atom than the base Persulfate (SO5 ), then the ion is named by adding the prefix per- and the suffix –ic o H2SO5 is persulfuric acid 2- If the ion has one less oxygen atom than the base Sulfite (SO3 ), then the ion is named with the suffix –ous. 2 o H2SO3 is sulfurous acid 2- If the ion has two less oxygen atoms than the base Hyposulfite (SO2 ), then the ion is named with the prefix hypo- and the suffix –ous. o H2SO2 is hyposulfurous acid Name the following: H2CO3 H3PO2 Cabonic acid Hypophosphorous acid HClO4 H3PO3 Perchloric acid Phosphorous acid 3 Page 11 Ionic Naming Worksheet 2 Fill in the table below with the correct ionic formula. Write the name of the compound in the box as well. The first one has been done for you as an example. Don’t forget that certain cations use Roman numerals in their names.
