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 Objectives:
To predict the ionic charge on a cation in a binary ionic compound.
To write systematic names and formulas for binary ionic compounds.

5. Binary Compounds NaCl sodium chloride (Na1+ Cl1-)
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 (Al I1-)
