1 NOMENCLATURE Name: Naming and Formula Writing for Binary Ionic Compounds: Notes: To Write Formulas: Practice: I. Give correct names for these binary ionic compounds KCl Potassium chloride MgO K 2 O AlCl 3 CaO BaS MgCl 2 Al 2 S 3 NaH SrF 2 ZnS MgI 2 RbBr CaSe Al 2 O 3 BaBr 2 Na 3 N CsCl Ca 2 C Mg 3 P 2 KI CaCl 2 II. Give correct formulas for these binary ionic compounds Calcium iodide Calcium hydride Magnesium fluoride Cadmium bromide Sodium Rubidium oxide Barium Lithium chloride Silver sulfide Cesium fluoride Magnesium phosphide Sodium chloride Barium oxide arsenide Calcium sulfide Potassium selenide Sodium iodide Lithium sulfide Calcium carbide Sodium hydride Magnesium

2 Naming and Formula Writing for Variable and Transition Elements aka STOCK System Notes: To Write Formulas: Practice: Which 3 transition elements are NOT variable and should NOT use Roman numerals? Write the names of each of the following compounds: CuF CrO 3 CuF 2 Cr 2 O 3 AuBr NiO PbI 2 VI 3 PbCl 4 SnO 2 Write the chemical formula for each of the given names: Manganese (VII) oxide Niobium (V) chloride Titanium (III) phosphide Palladium (IV) sulfide Platinum (II) fluoride Osmium (III) oxide Iridium (IV) Cobalt (II) chloride Iron (III) sulfide Gold (III) iodide

3 Cumulative Practice for Binary Ionic Compounds (Variable and non-variable) How do you decide whether to include roman numerals? Name each of the following compounds. FeCl 2 AuP Cu 2 O Mn 3 P 4 CrCl 6 Bi 2 O 3 BiBr 3 ZnCl 2 CoCl 2 PbO Fe 3 N 2 CrBr 3 AgCl Au 2 S 3 Bi 2 S 3 Sn 3 P 4 CrP Fe 2 S 3 Co 2 S 3 CoBr 3 Na 2 S Al 2 O 3 Au 3 N PbCl 4 BiBr 5 CrF 6 MgCl 2 NaCl RbI Fe 3 P 2 SnF 2 CrCl 3 BiF 5 BN Naming and Formula Writing for Compounds containing Polyatomic Ions To Write Formulas:

Write formulas for the following polyatomic compounds Bismuth (III) Silver sulfate Zinc sulfate Mercury (II) nitrite Cobalt (III) Strontium acetate Iron (III) Manganese(IV) hydroxide Barium phosphate nitrate Gold (I) nitrate Gold (I) Beryllium phosphate Mercury (I) Iron (II) sulfite Ammonium Mercury (II) nitrate Cobalt (III) Calcium hydroxide Sodium acetate Sodium phosphate Chromium (VI) phosphate Lithium nitrite Bismuth (V) Calcium nitrite Barium phosphate Copper (I) Lead (II) sulfite Hydrogen Perioxide

5 Formula Writing and Naming for Covalent Compounds Notes: Practice: SO 3 P 4 S 5 N 2 S SeF 6 PCl 3 Si 2 Br 6 BF 3 SCl 4 P 2 Br 4 NF 3 CO Cl 2 O 7 SiO 2 N 2 O 5 SF 6 P 2 Cl 3 NH 3 FI 3 NO 2 CBr 2 To write Formulas: Tetrahydride Carbon Tetrachloride Diphosphorus Trioxide Dichlorine Heptoxide Carbon dioxide Hexaboron monosilicide Chlorine dioxide Iodine pentafluoride trioxide Phosphorous triiodide Carbon disulfide Nitrogen monoxide Diboron tetrahydride Sulfur dibromide Tetraphsphorus decoxide Phosphorus pentachloride sulfur trioxide Carbon dioxide pentoxide Sulfur hexafluoride

6 Naming and Formula Writing for Acids If an ionic compound begins with hydrogen then it is an. It will dissociate in water. These compounds can be given an name. For example, we have learned the following names: 1. HCl is hydrogen chloride 2. HNO 3 is hydrogen nitrate 3. H 2 SO 3 is hydrogen sulfite Notice that the endings for these 3 ionic salts are ide, ate and ite We use these endings to determine the name as follows. Drop hydrogen out of the name and drop the ending. If the name ends in ide then it becomes hydro ic. If the name ends in ate then it becomes ic. If the name ends in ite then it becomes ous. So for the examples above: Formula Ionic name Acid name 1. HCl hydrogen chloride hydrochloric 2. HNO 3 hydrogen nitrate nitric 3. H 2 SO 3 hydrogen sulfite sulfurous 4. HClO 5. HClO 2 6. HClO 3 7. HClO 4 8. HBr 9. H 2 SO H 2 SO HMnO H 3 PO 4 15 HC 2 H 3 O HBrO H 3 BO HCN 20. H 2 Cr 2 O 7 Write the formulas for these s (they may or may not actually exist!): bromic nitrous hydrosulfuric chromic chlorous nitric sulfurous chromic

7 Acid Practice HCl H 2 C 2 O HNO 3 H 2 CO 3 H 2 SO 3 H 3 PO 4 HClO HC 2 H 3 O 2 HClO 2 HBrO 3 HClO 3 H 3 BO 3 HClO 4 HCN HBr H 2 Cr 2 O 7 H 2 SO 4 HF HMnO 4 H 2 S Nitrous Chromic Sulfuric Phosphoric Hydroiodic Carbonic Acetic Hydrofluoric Nitric Chloric Chlorous Perchloric Cumulative Naming and Formula Writing Review Lots of things to think about! 1. Is it ionic or covalent? 2. If Ionic, is it variable? If so roman numerals 3. Does it start with H? If so, its an!
