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
