  1. Nomenclature: Type I Binary Ionic-metal and nonmetal type I group 1,2,13 and nonmetal Type II Binary Ionic transition metals and nonmetals Covalent- nonmetal and nonmetal Polyatomic Ion Acid Naming and Formulas

  2. Type I Characteristics: metal cation (Group 1,2,13, Ag+1 and Zn+2) + nonmetal anion Rules: 1. Name the metal first and nonmetal second. 2. Metal takes element name. 3. Nonmetal takes root element name plus suffix –ide. Examples: NaCl Sodium chloride CaF2 Calcium fluoride AlBr3 Aluminum bromide Binary Ionic Naming

  3. Writing Type I Ionic Formulas • RULES • SCSR: Symbols, Charges (group charges), Switch (no +/- signs), Reduce! • Examples: Magnesium iodide • MgI2 Aluminum fluoride AlF3 Calcium sulfide CaS

  4. Type II Characteristics: metal cation (transition metals, Sn and Pb) + nonmetal anion Rules: Same as Type1 + Roman Numeral for Charge Anion group charge x subscript = total negative charge Total (-) charge = Total (+) charge Total (+) charge/subscript = cation charge Examples: FeCl3 Iron (III) chloride Fe2O3 Iron (III) oxide CuBr Copper (I) bromide CuBr2 Copper (II) bromide Binary Ionic Naming

  5. Writing Type II Ionic Formulas Rules SCSR Roman Numeral is Metal’s Charge Examples: Copper (I) nitride Titanium (III) chloride

  6. Type III Characteristics: (only nonmetals) nonmetal + nonmetal Rules: 1. Name first element first and second element second. 2. First element takes element name and second element is named like an anion w/ -ide suffix. 3. Use prefixes to indicate the number of atoms for element. 4. Never use the mono- prefix on the first element. Prefixes: 1 mono- 6 hexa- 2 di- 7 hepta- 3 tri- 8 octa- 4 tetra- 9 nona- 5 penta- 10 deca- Examples: CO N2O Binary Covalent Naming

  7. Writing Covalent Formulas • Prefixes in the name are converted to subscripts attached to the same element. • Examples: Sulfur hexafluoride Tetraphosphorus decoxide Dihydrogen monoxide

  8. Polyatomic Ion Naming • Characteristics: compound contains more than 2 elements • Polyatomic Ion (PAI) – 2 or more covalently bonded atoms with an overall charge • Types: • Type I Metal + PAI • Type II Metal + PAI • PAI + PAI • PAI + Nonmetal

  9. Rules: Identify the PAI If the First Ion is a: *Type I M- element name *Type II M- element name w/ Roman numeral *PAI- polyatomic ion If the Second Ion is a: PAI- polyatomic ion name NM- element root w/ -ide. 4. Do NOT use prefixes. Examples: NaNO3 FeSO4 NH4Cl NH4NO3 Polyatomic Ion Naming

  10. Writing PAI Formulas For the cation (+): 1. Write the symbol. 2. Charges: Type I M – group charge Type II M – roman numeral, then PAI For the anion: 1. Write the symbol. 2. Charges: PAI Nonmetal (single) – group charge • Then Switch and Reduce!!! Examples: Sodium hydroxide Copper (II) nitrate Ammonium Hydroxide Ammonium chloride

  11. Acids with Oxygen (oxyacids) Based on the PAI with changes to the endings. -ate  -ic -ite  -ous Acid is always placed at the end of the name. Hydrogen is NOT part of the name. Acids without Oxygen hydro-(anion root)-ic acid Anion may be a single nonmetal or a PAI that does not contain oxygen. Examples: HBr H3PO4 Acid NamingCharacteristics: Hydrogen is the first element

  12. Writing Acid Formulas • First ion: - ALWAYS hydrogen (H+) • Second ion: - PAI – memorized charge (p.100) - Nonmetal (single) – group charge • Then Switch and Reduce! Examples: Hydrochloric acid Sulfuric acid
