Nomenclature

  • ==ionic nomenclature==   * ^^metal^^ (1A, 2A, Al+3, Zn+2, Cd+2, Ag+1) and ^^nonmetal^^

     1. write metal name      * is it a transition metal? (NO)   2. write non-metal name      * ending changes to -ide   * ^^metal^^ (1A, 2A, Al+3, Zn+2, Cd+2, Ag+1) and ^^polyatomic ion^^

     1. write metal name      * is it a transition metal? (NO)   2. write polyatomic ion name      * DO NOT CHANGE NAME   * ^^transition metals, Sn, Pb^^ and ^^nonmetal^^

     1. write transition metal name   2. use roman numeral to indicate charge on transition metal      * +1 (I)      * +2 (II)      * +3 (III)      * +4 (IV)   3. write nonmetal name with -ide ending

  • ==covalent nomenclature==   * ^^two nonmetals^^ together

     1. write first nonmetal name - non change   2. write second nonmetal name with -ide ending   3. use prefix to indicate numbers of atoms of each non metal   * prefixes

          1. mono- *not used for first nonmetal - ex. NO → Nitrogen Monoxide      2. di-      3. tri-      4. tetra-      5. penta-      6. hexa-      7. hepta-      8. octa-      9. nona-     10. deca-     * “oo” drop first o -- ex. NO → Nitrogen Mon(o)oxide     * “ao” drop a

  • ==acid nomenclature==   * chemical formula begins with H+   * based on anion (second part, H2SO3)     * ends in -ide → hydro-root name of ion-ic acid       * ex. HCl → hydrochloric acid     * ends in -ite → root name of ion-ous acid       * ex. HClO2 → chlorous acid     * ends in -ate → root name of ion-ic acid       * ex. HClO3 → chloric acid
  • questions   * is there a metal?     * yes - is it a transition metal       * no - no parentheses       * yes - (roman numerals)     * no - prefix-first, prefix-last-ide   * does the formula begin with H+?     * yes - acid, follow through based on anion
