Nomenclature

(A fancy way to say Naming)

PO43-phosphate ionC2H3O2-acetate ionPredicting Charges on Monatomic IonsKNOW THESE !!!!

+1 +2 -3 -2 -1 0Cd+2C +/- 4NO3-nitrate ionNO2-nitrite ion

Polyatomic IonsYou can make additional polyatomic ions by adding a H+ to the ion!CO3 -2 is carbonateHCO3 is hydrogen carbonate

H2PO4 is dihydrogen phosphateHSO4 is hydrogen sulfatePolyatomic IonsTwo Families of Compounds:IonicBinary (with and without transition metal)TernaryMolecularCATION -- Metal(POSITIVELY CHARGED ION) + ANION -- Nonmetal(NEGATIVELY CHARED ION) COMPOUNDA neutral compound What is an ionic compound?

Na++ Cl- NaClBinary Ionic CompoundsTwo elements (one metal and one nonmetal; without transition metal)

Naming: Use name of metal, then put in name of nonmetal with ide as the suffix.Calcium fluorideCa2+ + 2 F- ---> CaF2Naming Binary Ionic CompoundsExamples:NaClZnI2Al2O3sodium chloride

zinc iodide

aluminum oxide

Learning Check Write the correct formula for the compounds containing the following ions:1. Na+, S2- a) NaS b) Na2Sc) NaS22. Al3+, Cl- a) AlCl3 b) AlCl c) Al3Cl3. Mg2+, N3- a) MgN b) Mg2N3c) Mg3N2

Binary Ionic CompoundsTwo elements (one metal and one nonmetal; with transition metal)

Naming: Use name of metal, then put in name of nonmetal with ide as the suffix.

**Difference** Must input Roman NumeralsManganese (II) ChlorideMn2+ + 2 Cl- MnCl2Transition MetalsElements that can have more than one possible charge MUST have a Roman Numeral to indicate the charge on the individual ion.1+ or 2+ 2+ or 3+Cu+, Cu2+ Fe2+, Fe3+copper(I) ion iron(II) ion copper (II) ion iron(III) ion Transition metals (except Ag, Zn, Cd, and Al) require a Roman Numeral.

Learning Check Complete the names of the following binary compounds with variable metal ions:FeBr2iron (_____) bromideCuClcopper (_____) chlorideSnO2_______ ( _____ ) __________ Fe2O3_______ ( _____ ) __________Hg2S_______ ( _____ ) __________

An ionic compound with a polyatomic ion!

CarbonateSulfateNitrateAmmoniumAcetateHydroxideTernary Ionic CompoundsNaming Ternary CompoundsContains at least 3 elementsThere MUST be at least one polyatomic ion(it helps to circle the ions)Examples:NaNO3Sodium nitrateK2SO4Potassium sulfateAl(HCO3)3Aluminum bicarbonateor Aluminum hydrogen carbonateTernary Ionic NomenclatureSodium SulfateNa+ and SO4 -2Na2SO4
