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)
  1. 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)
  1. 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)
  1. 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
