1 Naming Compounds Flowchart
LOOK ON BACK FOR EXAMPLES OF EACH! Naming Compounds Flowchart Is there a METAL in the compound? YES (type 1, 2) NO Is METAL a TRANSITION METAL? Is first element Hydrogen? NO (type 1) YES (type 2) NO (type 3) YES (Acid) Acid Count different elements Count different elements H + Element Hydro + root anion + -ic acid H + Polyatomic ion Poly ion ending in –ate Root anion ic acid Poly ion ending in –ite Root anion ous acid Root anion = 1st part of polyatomic ion name or element 2 elements Metal / Nonmetal Ionic Binary 3 or more elements Metal / Poly Ion Ionic Ternary 2 elements Tran Metal / Nonmetal Ionic Binary 3 or more elements Tran Metal / Poly Ion Ionic Ternary Name metal first Name nonmetal second and change ending to “-ide” Name transition metal first Determine charge of transition metal and write as Roman Numeral after name Name nonmetal second and change ending to “-ide” Count the different elements Only 1 element Diatomic molecule 2 elements Covalent Binary (type 3) Name metal first Name polyatomic ion second DO NOT change ending to “-ide” Name transition metal first Determine charge of transition metal and write as Roman Numeral after name Name polyatomic ion second DO NOT change ending to “-ide” Br2 I2 N2 Cl2 H2 O2 F2 Name same as periodic table name Name first element, using Greek prefixes (except “mono-”) (Prefixes indicate how many of each element is in the compound) Name second element, using prefixes (including “mono-”) Change ending to “-ide”

2 Polyatomic Ion List Greek PREFIXES (type 3) Answer: Iron III oxide
DETERMINING THE CHARGE OF A TRANSITION METAL Find the total charge of the Anion Anion Oxidation # x Anion Subscript Determine charge of Transition Metal Total Anion charge ÷ Metal subscript Transition metal charge is always positive (+) ROMAN NUMERALS (type 2) I one II two III three IV four V five Greek PREFIXES (type 3) Covalent Compounds ONLY: Look at subscripts to determine how many of each element you have One mono- Two di- Three tri- Four tetra- Five penta- Six hexa- Seven hepta- Eight octa- Nine nona- Ten deca- Example: Polyatomic Ion List Step 1: x 3 = -6 Step 2: ÷ 2 = -3 Step 3: Charge of Fe Answer: Iron III oxide IONIC COMPOUNDS EXAMPLES Metal/Nonmetal (type 1) KCl __________________________ Al2O __________________________ Metal/Polyatomic Ion (type 1) Mg(NO3) __________________________ NaC2H3O __________________________ Transition Metal/Nonmetal (type 2) Fe2O __________________________ CuCl __________________________ Transition Metal/Polyatomic Ion (type 2) CuCrO __________________________ Zn(OH) __________________________ COVALENT COMPOUNDS EXAMPLES Nonmetal/Nonmetal (type 3) P2O __________________________ CCl __________________________ Metal/Polyatomic Ion (diatomic) Cl __________________________ Br __________________________ ACID EXAMPLES H + Element HCl ________________________________ H3P ________________________________ H + Polyatomic Ion H2SO4 ________________________________ H2SO3 ________________________________ H3PO4 ________________________________
