Adsorption is the adhesion of atoms, ions or molecules from a gaseous, liquid or dissolved solid to a surface. This mechanism produces an adsorbent layer on the adsorbent surface. This method varies from the absorption in which, respectively, a substance (the absorbent) is dissolved or permeated by a liquid or solid (the absorbent). The adsorption is a product of surface energy, analogous to surface stress. For a bulk substance, all the bonding properties of the material's constituent atoms (whether ionic, covalent or metallic) are filled in by other atoms in the sample. Atoms on the adsorbent surface, however, are not completely surrounded by other adsorbent atoms, and can therefore attract adsorbents.
