Naming Compounds

Naming Compounds. Naming Ionic Compounds. Ionic compounds contain a metal and a nonmetal Name the metal first, then the nonmetal as -ide Examples: NaCl sodium chloride ZnI 2 zinc iodide Al 2 O 3 aluminum oxide. What are the names of the following compounds? Na 3 N sodium nitride

  1. Naming Compounds

  2. Naming Ionic Compounds Ionic compounds contain a metal and a nonmetal Name the metal first, then the nonmetal as -ide Examples: NaCl sodium chloride ZnI2 zinc iodide Al2O3 aluminum oxide

  3. What are the names of the following compounds? Na3N sodium nitride KBr potassium bromide Al2O3 aluminum oxide MgS magnesium sulfide

  4. Transition Metals Most form more than one positive ions with these charges: 1+ 2+ 1+ or 2+ 2+ or 3+ Ag+Cd2+ Cu+,Cu2+Fe2+, Fe3+ silver cadmium copper(I) ion iron(II) ion ion ion copper (II) ion iron(III) ion

  5. Names of cations with more than one charge… Use a Roman number after the name of a metal that forms two or more ions Transition metals and the metals in groups 4A and 5A FeCl3(Fe3+) iron (III) chloride CuCl (Cu+ ) copper (I) chloride SnF4 (Sn4+) tin (IV) fluoride PbCl2 (Pb2+) lead (II) chloride Fe2S3 (Fe3+) iron (III) sulfide

  6. Name the following compounds: CaO calcium oxide SnCl4 tin(IV) chloride Co2O3 cobalt (III) oxide

  7. Complete the names of the following compounds with variable metal ions: FeBr2 iron (II) bromide Cu2O copper (I) oxide SnCl4 tin (IV) chloride Fe2O3 iron (III) oxide CuS copper (II) sulfide

  8. Polyatomic Ions A group of atoms with an overall charge. Refer to your handout… NH4+ Ammonium OH- Hydroxide NO3- Nitrate NO2- Nitrite CO32- Carbonate

  9. Naming Ternary Compounds Contain at least 3 elements Name the nonmetals as a polyatomic ion Examples: NaNO3 Sodium nitrate K2SO4 Potassium sulfate

  10. Identify the correct names: Ca(HCO3)2 calcium bicarbonate CaCO3 calcium carbonate Ca3(PO4)2 calcium phosphate Na2CO3 sodium carbonate MgSO3 magnesium sulfite MgSO4 magnesium sulfate

  11. Naming Covalent Compounds Two nonmetals End the last element in -ide Add prefixes to show more than 1 atom Prefixes: mon- 1 penta- 5 di- 2 hexa- 6 tri- 3 tetra- 4

  12. CO carbon monoxide CO2 carbon dioxide PCl3 phosphorus trichloride CCl4 carbon tetrachloride N2O dinitrogen monoxide

  13. Acids without the presence of oxygen, the name is written as: Hydro(anion)ic acid Hydrosulfuric acid – H2S Hydrobromic acid - HBr Hydrocyanic acid – HCN

  14. If the acids do contain oxygen, the method of naming them changes. If the anion ends in “-ate”, the suffix that is added to the chemical name is “-ic”. Nitric acid HNO3 Sulfuric acid H2SO4 Phosphoric acid H3PO4 If the anion ends in “-ite”, the suffix is “-ous” Nitrous acid HNO2 Sulfurous acid H2SO3
