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
  3. ^^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
  3. ^^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
  4. 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
