(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
Iron (III) hydroxideFe+3 and OH-Fe(OH)3
Ammonium carbonateNH4+ and CO3 2(NH4)2CO3Learning Check 1. aluminum nitrate a) AlNO3 b) Al(NO)3 c) Al(NO3)32. copper(II) nitrate a) CuNO3b) Cu(NO3)2c) Cu2(NO3)3. Iron (III) hydroxide a) FeOHb) Fe3OHc) Fe(OH)34. Tin(IV) hydroxide a) Sn(OH)4 b) Sn(OH)2 c) Sn4(OH)
