(Honors) Practice: Writing formulas and names for compounds

First determine if the compound is ionic or covalent. Then write the formula using the ionic method or covalent method. To make a subscript, highlight the number and formatting options will pop up. Click on the subscript option (looks like x2). Name Ionic or Covalent? Formula Sodium fluoride ionic NaF Ammonium phosphate ionic (NH4)3PO4 Rubidium acetate ionic RbC2H3O2 Copper (II) sulfide ionic CuS Carbon tetrachloride covalent CCl4 Dinitrogen heptachloride covalent N2Cl7 Magnesium oxide ionic MgO Carbon trioxide covalent CO3 Barium nitride ionic Ba3N2 Iron (II) sulfate ionic FeSO4 Lithium sulfide ionic Li2S Cobalt (III) Nitrite ionic Co(NO2)3 Nitrogen tribromide covalent NBr3 Nitrogen pentoxide covalent NO5 First determine if the compound is ionic or covalent. Then write the name using the ionic method or covalent method. Formula Ionic or Covalent? Name MgBr2 ionic magnesium bromide PbSO3 ionic lead (II) sulfite N2F6 covalent dinitrogen hexafluoride FeCl3 ionic iron (III) chloride CdI2 ionic cadmium iodide SiF4 covalent silicon tetrafluoride SnO2 ionic tin (IV) oxide P2S3 covalent diphosphorus trisulfide Ag2S2O3 ionic silver thiosulfate AgF ionic silver fluoride NO covalent nitrogen monoxide CrO3 ionic chromium (VI) oxide NH4IO3 ionic ammonium iodate K2O ionic potassium oxide CsCl ionic cesium chloride
