Naming Binary Ionic Compounds

 

 

Rules

1. The Cation (positive ion) is named first, the Anion second.

2. Monoatomic Cations take the element name

                             Na+ --> Sodium

                             Ca2+ --> Calcium

3. Monoatomic Anions take the elements name and ends with "-ide"

                             Cl- --> Chloride

                             NaCl --> Sodium Chloride

                             Li3N --> Lithium Nitride

Note** Greek prefixes are not used to indicate the number of atoms of each element in the formula unit for the compound

 (e.g., Na2O is named "sodium oxide" not "disodium oxide", or "disodium monoxide").
