NamingCompounds

1.Binary Compounds:Made up of only 2 elements

• A. Metal & Non-metal
  • Name metal
  • Name non-metal
  • Drop end of non-metal name and add suffix -ide
  • Backwards
    • Write down symbol of metal & charge
    • Write down symbol of non-metal & charge
    • Total "+" charge equals "-" charge

• B. 2 Non-metals
  • Prefix to denote number of atoms of the first element (if number is greater than 1)
  • Name first element
  • Prefix to denote number of atoms of the second element (if number is 1, use "mono"), see table below
  • Add suffix "ide"
  • Backwards:
    • Write down symbol for each element & add appropriate number of prefixes

• Name metal
• Name polyatomic (no Prefixes)
• Backwards:
  • Give down appropriate symbols and charge
  • Balance charges
  • Use paranthesis if subscript is greater than 1, and with polyatomics

3. Compounds containing metals w/ more than one possible charge

• Name metal w/ appropriate Roman Numeral (from apporopriate charge)
• Name non-metal or ployatomic
• Backwards:
  • Write down symbol and charge for metal & anion (metal charge from Roman numeral)
  • Balance charges to determine subscripts

4. Acids (all acids begin w/ "H"): Name acids by anion Chemical Formula to Chemical Name

• A. Anion ends in "ide"
  • Use prefix "hydro-"
    • Name anion
    • Change suffix "ide" to "ic"
    • Add word "acid"
• B. Anion ends in "ite"
  • Name anion
  • Change suffix from "ite" to "ous"
  • Add word "acid"
• C. Anion ends in "ate"
  • Name anion
  • Change suffix from "ate" to "ic"
  • Add word "acid"

• Find prefix & suffix and determine name of anion
• Find anion symbol(s) charge from anion name
• Balance the negative charge of anion with "H⁼"
• Write chemical formula, anion will always have subscript 1, it is just what subscript of H is.
