The two elements most commonly involved in cation substitution are sodium (Na) and potassium (K). These alkali metals often replace one another in various mineral structures due to their similar ionic sizes and charges, allowing for isomorphism. This substitution can significantly influence the physical and chemical properties of minerals, including their stability and reactivity.
Cation substitution is a process in which one type of cation (positively charged ion) in a crystal lattice is replaced by another cation with similar size and charge. This substitution can occur in minerals and other solid materials, influencing their properties, such as electrical conductivity, color, and stability. It is commonly observed in ionic compounds and plays a significant role in geochemistry and materials science. This phenomenon can lead to variations in mineral composition and behavior in geological processes.
An oxonium cation is a polyatomic cation with a charge of +1 with a central oxygen bonded to three groups or elements Examples:- H3O+ is the oxonium cation, (C2H5)3O+ is the triethyloxonium cation.

Alkaline-earth elements form cations.
The compound AgCrO4 is named silver chromate. It consists of silver (Ag) as the cation, and chromate (CrO4) as the anion. The name is derived from the combination of the names of the two elements involved.
