Concept introduction: An ionic compound that contains only two elements, one present as a cation and one as an anion, is called a binary ionic compound. These compounds are of three types:
- Type I binary ionic compound: which contain ions of metals that can show only one type of oxidation state.
- Type II binary ionic compound: which contain ions of metals that can show more than one type of oxidation state.
- Type III binary ionic compound: contains ions that are generated from non metals.

Answer to Problem 8A
Correct nomenclature of
Explanation of Solution
Rules set for constituting nomenclature of binary ionic compounds are as follows:
- Position of both cation and anion forming element has to be identified for idea of their oxidation state.
- Always the cationic species name is retained and placed first in nomenclature.
- After the cation name, anion name is placed with suffix ‘-ide’ at the end of its root name.
- The oxidation state is expressed as roman numeral after cation name, enclosed in bracket.
