 Monolayer

A monolayer is a single layer of chemical atoms or molecules. In the Langmuir adsorption model, a complete monolayer occupies every adsorption site; partial surface coverage leaves vacancies within that first layer. One layer need not mean one molecule per surface chemical atom.

A monolayer refers to a single, contiguous layer of atoms, molecules, or cells that is one unit thick. This term is commonly used in various scientific fields, including materials science, biology, and chemistry.
