1929 J. A. Becker in Trans. Electrochem. Soc. 55 154 Because of the frequent use of the terms ‘adsorbed ion’ and ‘adsorbed atom’ we would suggest that they be abbreviated to adion and adatom.

1931 Jrnl. Amer. Chem. Soc. 53 489 One oxygen adatom may hold more than one cesium atom.

1963 J. P. Hirth & J. M. Pound Condensation & Evaporation 43 Nucleation..may occur by either direct addition from the vapor or surface diffusion of an adatom.

1999 I. Kostov & R. I. Kostov Crystal Habits Minerals v. 81 Adsorption of impurities (adatoms) on K and S faces may lead to growth forms with bright crystal faces.
