Naming Compounds

Nomenclature is the system used in chemistry for the naming of different compounds and molecules. 

Ionic Compounds

Metals lose electrons to be positive ions, whereas nonmetals gain electrons to become negative ions. 

Naming Binary Ionic Compounds

An ionic compound involves the bond between a cation (positive ion) and an anion (negative ion).
