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
