Identifying Compounds
Ionic compounds are composed of a metal ion and a nonmetal ion. Either or both of these ions may be replaced with a polyatomic ion. Examples: KCl Na2S NH4F CaCO3 NH4NO3
Molecular (also known as covalent) compounds are composed of nonmetal (and sometimes metalloid) elements only. No metals!!!! Examples: CO2 PCl3 NO SiO2 CCl4
Acids are composed of a hydrogen ion and a nonmetal ion or polyatomic ion. Examples: HCl HF H2S HNO3 H2SO4
Bases are composed of a metal ion and a hydroxide (OH-) ion. Examples: LiOH Al(OH)3 Ba(OH)2 NaOH KOH

Ionic Compound Worksheet
Helpful hints: • The simplest type is composed of a metal + nonmetal. Examples: NaCl, K2O,
MgBr2 • Ionic compounds may also contain polyatomic ions. Examples: NaNO3, NH4Cl,
K2SO4 • Ionic compounds are named simply by naming the two ions, in order. Positive
(cation) always comes 1st! Negative (anion) always comes 2nd! • Remember that some transition metals require a Roman numeral to indicate the
charge when 2 or more possibilities exist. Example: copper (I) = Cu+, and copper (II) = Cu2+.
• Ionic compound formulas are written by “criss-crossing” the charges on the ionsand reducing subscripts if possible.
