Final answer:
NaCl and CaCl₂ are examples of binary ionic compounds, while NO, NO₂, and N₂O are examples of binary molecular compounds.
Step-by-step explanation:
An example of a binary ionic compound is NaCl, which is composed of the monatomic metal cation Na+ and the monatomic nonmetal anion Cl-. Another example is CaCl₂, which consists of the monatomic cation Ca²+ and monatomic anions Cl-. On the other hand, a binary molecular compound is composed of two nonmetal elements, such as NO, NO₂, and N₂O, which are all compounds of nitrogen and oxygen but have differing properties and must be named distinctly to avoid confusion.
