  1. Inorganic Compounds- nomenclature University of Lincoln presentation This work is licensed under a Creative Commons Attribution-Noncommercial-Share Alike 2.0 UK: England & Wales License

  2. INORGANIC COMPOUNDS Compounds composed of elements other than carbon. Associated with the nonliving portion of the world This work is licensed under a Creative Commons Attribution-Noncommercial-Share Alike 2.0 UK: England & Wales License

  3. NOMENCLATURE OF INORGANIC COMPOUNDS Ionic Compounds Molecular Compounds Acids This work is licensed under a Creative Commons Attribution-Noncommercial-Share Alike 2.0 UK: England & Wales License

  4. NAMING IONIC COMPOUNDS CATIONS ( POSITIVE IONS) A. Cations formed from metal atoms have the same name as the metal. Na+ sodium ion Zn2+ zinc ion Al3+ aluminum ion This work is licensed under a Creative Commons Attribution-Noncommercial-Share Alike 2.0 UK: England & Wales License

  5. B. If a metal can form cations of different charges, the positive charge is given by a Roman numeral in parenthesis following the name of the metal. Fe2+ iron (II) ion Cu+ copper (I) ion Fe3+ iron (III) ion Cu2+ copper (II) ion This work is licensed under a Creative Commons Attribution-Noncommercial-Share Alike 2.0 UK: England & Wales License

  6. Ions with different charges exhibit different properties, such as color. Most of the metals that have variable charges are transition metals. This work is licensed under a Creative Commons Attribution-Noncommercial-Share Alike 2.0 UK: England & Wales License

  7. Apply –ous or –ic The endings represent the lower and higher charged ions, respectively. Fe2+ ferrous ion Cu+ cuprous ion Fe3+ ferric ion Cu2+ cupric ion This work is licensed under a Creative Commons Attribution-Noncommercial-Share Alike 2.0 UK: England & Wales License

  8. IONIC CHARGES OF REPRESENTATIVE ELEMENTS This work is licensed under a Creative Commons Attribution-Noncommercial-Share Alike 2.0 UK: England & Wales License

  9. FORMULAS AND NAMES OF COMMON METAL IONS WITH MORE THAN ONE IONIC CHARGE This work is licensed under a Creative Commons Attribution-Noncommercial-Share Alike 2.0 UK: England & Wales License

  10. C. Cations formed from nonmetals have names that end in –ium NH4+ ammonium ion H3O+ hydronium ion This work is licensed under a Creative Commons Attribution-Noncommercial-Share Alike 2.0 UK: England & Wales License

  11. EXERCISES: Name each of the following: Sn2+ Sn4+ K+ Ba2+ Co2+ Co3+ This work is licensed under a Creative Commons Attribution-Noncommercial-Share Alike 2.0 UK: England & Wales License

  12. Sn2+ Tin (II) ion • Sn4+ Tin (IV) ion • K+ Potassium ion • Ba2+ Barium ion • Co2+ Cobalt (II) ion • Co3+ Cobalt (III) ion This work is licensed under a Creative Commons Attribution-Noncommercial-Share Alike 2.0 UK: England & Wales License

  13. 2. ANIONS (NEGATIVE IONS) A. Monoatomic (one-atom) anions have names formed by replacing the ending of the name of the element with –ide H- O2- N3- OH- Hydride ion Oxide ionNitride ion Hydroxide ion This work is licensed under a Creative Commons Attribution-Noncommercial-Share Alike 2.0 UK: England & Wales License

  14. B. Polyatomic (many-atoms) anions containing oxygen have names ending in –ate or –ite These are called oxyanions -ate is used for the most common oxyanion of an element -ite is used for an oxyanion that has the same charge but one less O atoms NO3- nitrate ion SO42- sulfate ion NO2- nitrite ion SO32- sulfite ion This work is licensed under a Creative Commons Attribution-Noncommercial-Share Alike 2.0 UK: England & Wales License

  15. Prefixes are used when the series of oxyanions of an element extends to four members, as with halogens The prefix per- indicates one or more O atom than the oxyanion ending in –ate The prefix hypo- indicates one less O atom than the oxyanion ending in –ite This work is licensed under a Creative Commons Attribution-Noncommercial-Share Alike 2.0 UK: England & Wales License

  16. ClO4- perchlorate ion (one more O atom than chlorate) ClO3-chlorate ion ClO2- chlorite ion (one less O atom than chlorate) ClO- hypochlorite ion (one less O atom than chlorite) This work is licensed under a Creative Commons Attribution-Noncommercial-Share Alike 2.0 UK: England & Wales License

  17. C. Anions derived by adding H+ to an oxyanion are named by adding as a prefix the word hydrogen or dihydrogen CO32- carbonate ion HCO3- hydrogen carbonate ion PO43- phosphate ion H2PO4- dihydrogen phosphate ion This work is licensed under a Creative Commons Attribution-Noncommercial-Share Alike 2.0 UK: England & Wales License
