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!!!!
PCl3
NO
SiO2
CCl4
Examples: CO2
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
