Ionic Nomenclature

Ionic Nomenclature: 

Ionic Nomenclature When naming an ionic compound, follow this basic formula: Al2O3 Name of cation Name of anion Aluminum Oxide The anion will always have the suffix –ide, unless it’s a polyatomic ion of a different name. Cations have no change made to their name.

Examples:: 

Examples: Oxygen ionized becomes oxide. Iodine ionized becomes iodide. Nitrogen ionized becomes nitride. I think the pattern is fairly obvious.  + ide

Cations from the d-block elements: 

Cations from the d-block elements When your cation is a metal from the d-block (for example, Fe) you need to include its charge in roman numerals enclosed in parenthesis. Since the ionization charges of d-block elements are not apparent from the periodic table, the ions charge will either be given or can be deduced by the charge of the anion.

Example:: 

Example: FeO Oxygen has an ionization energy of -2. Since there is a 1:1 ratio of Fe:O, iron must have a charge of +2. Therefore, iron’s ionized name is ‘iron (II)’. Iron (II) oxide
