LEWIS DOT DIAGRAMS (STRUCTURES) FOR ATOMS AND …



Classifying Ionic versus Covalent / Lewis Dot Structures of AtomsClassify the following compounds as ionic ([metal or ammonium ion] + [non-metal or polyatomic ion]), covalent (nonmetal+ nonmetal).CaCl2CO2H2OBaSO4K2ONaFNa2CO3CH4SO3LiBrMgONH4ClHClKINaOHNO2AlPO4FeCl3P2O5N2O3CaCO3Draw Lewis dot structures for each of the following atoms:AluminumSiliconPotassiumXenonSulfurCarbonHydrogenHeliumBromineSeleniumNitrogenBariumChlorineGalliumArgonLewis Dot Structure for Ions/ Typical ChargesDetermine the common oxidation number (charge) for each of the following ions, and then draw their Lewis Dot Structure. Don’t forget to show brackets and charge on your LDS for ions!**Note: Notice that non-metals get the –ide ending to their names when they become an ion.Aluminum ionSilicon ionPotassium ionFluoride ionSulfide ionCarbide ionHydrogen ionCesium ionBromide ionChloride ionGallium ionZinc ion (+2)Silver ion (+1)Oxide ionBarium ionPredict the common oxidation numbers (CHARGE) for each of the following elements when they form ions. ALSO - there may be more than one!!! Especially on those pesky non-metals in Groups 14 & 15.ElementCommon Oxidation Number(s)ElementCommon Oxidation Number(s)RubidiumSulfurArsenicBismuthStrontiumTinCadmium (+2)PhosphorousZinc (+2)Silver (+1)LeadBromineAluminumGallium Determining Ionic FormulasFill in the chart below. You will need to determine the number of cations and anions which need to mix for a formula. ClONSPBrNaRaKCaMgZn(+2)HLewis Dot Structure for Ionic CompoundsFill in the chart below.

REMEMBER THE NAMING PATTERN FOR ANIONS – THEY HAVE AN –IDE ENDING!This means you need to figure out how many of each ion you need to balance out the charge!Calcium bromideAluminum bromideMagnesium oxideRubidium nitrideAluminum selenideCesium sulfideStrontium phosphideBeryllium nitridePotassium iodideLithium silicide ................
