  3. Four Types of Naming • Binary compounds • Ternary compounds • Coordination compounds • Organic compounds Contain only two types of elements Contain more than two types of elements These will not be covered We will cover these in a separate unit

  4. Binary Compounds Metals (fixed oxidation) + Nonmetals

  5. Binary Compounds Binary compounds that contain a metal of fixed oxidation number (group 1, group 2, Al, Zn, Ag, etc.), and a non-metal. To name these compounds, give the name of metal followed by the name of the non-metal, with the ending replaced by the suffix –ide. Examples: NaCl sodium chloride (Na1+ Cl1-) CaS calcium sulfide (Ca2+ S2-) AlI3 aluminum iodide (Al3+ I1-)
